Do tropical fish yearn for snow

Tropical fish are commonly found in warm waters, so it is unlikely that they have an innate yearning for snow. Also, specific physiological and behavioral adaptations enable tropical fish to survive and thrive in warm waters. They rely on stable warm temp to maintain metabolism, digestion, and overall health. If exposed to cold temp, they are going to face stress, weakened immune system, or even illness or death.

How to breed tropical fish in winter

Keeping tropical fish in winter can be challenging, because cold weather, causing water temperature fluctuation can be a threat to fish growth. In this segment, let’s learn some tips to breed tropical fish in winter.

Monitor water temperature

A stable and warm water temp is vital for tropical fish. Typically, the water temp should be kept in the range of 75-80℉(24-27℃). Hence, an aquarium heater and an aquarium thermometer may be necessary for tropical fish tanks in winter.

An aquarium heater helps to maintain stable water temp, while a thermometer can check real-time water temperature. But if your heater has a built-in thermometer, it is viable not to add a thermometer.

Insulate your aquarium

Insulating your aquarium is helpful to stabilize water temp and prevent heat loss, especially in case of power loss. You can place insulating material around the sides and back of the aquarium. For instance, foam and polystyrene sheets. But do not completely cover the top of your aquarium, allowing for gas exchange.

Avoid drafts and cold spots

Keep the aquarium away from windows, doors, or areas with drafts. Cold drafts can cause temperature fluctuations and stress the fish. Also, avoid placing the tank near heating vents or radiators, as the direct heat can be harmful.

Adjust lighting

Due to the shorter daylight hours in winter, adjustments to lighting hours would be required. Generally, you can keep the light on for around 10–12 hours per day. It helps to maintain a consistent light cycle for tropical fish.

Monitor water quality

Keeping great water quality is essential for the health of tropical fish. Typically, regularly test the water parameters, such as pH, ammonia, nitrite, and nitrate levels. Moreover, routine water changes can remove waste and improve water agitation. Each time you change water, cold tap water should be avoided. You should warm the water to room temperature.

Observe fish behavior

Keep a close eye on your fish’s behavior and appearance. Once you notice signs of stress, such as decreased activity, loss of appetite, or unusual swimming patterns. Find the root cause immediately and take measures to deal with it.

How often to feed the tropical fishes

Commonly, twice or three times each day is viable. But, actually, the feeding frequency can be determined by fish species, age, size, behavior, and their needs. In this part, let’s take a look at some pointers.

Feeding amount

Feeding smaller meals each time rather than a large amount of food. Just keep in mind – small portions for multiple times.

Fish size and age

Young fish with higher metabolisms require more frequent feeding. As they grow up, you can gradually reduce the feeding amount and frequency.

Fish behavior

Consuming food fast within a few minutes may indicate that fish are hungry and need more food. However, if there is uneaten food after feeding, it may mean overfeeding, then you can reduce the feeding amount or frequency.

Balanced diet

A varied and balanced diet prevents nutrient deficiency and promotes overall health. The available food includes worms, brine shrimp, high-quality commercial fish flakes or pellets, frozen, freeze-dried, or live foods, etc. Occasionally, you can feed tropical fish some vegetables.

The smallest tropical fish

To begin with, we will list some smallest tropical fish.

• Endler’s Livebearer (Poecilia wingei): a popular choice for nano aquariums.
• Ember Tetra (Hyphessobrycon amandae): striking red-orange coloration adds a splash of brightness to any aquarium.
• Celestial Pearl Danio (Danio margaritatus): incredibly small, about 1 inch.
• Pygmy Corydoras (Corydoras pygmaeus): peaceful bottom-dwelling fish and generally kept in small groups.
• Least Killifish (Heterandria formosa): peaceful and adaptable to various water conditions.

Next, we will cover some interesting facts about the smallest tropical fish.

Nano tank delights

Due to their size, the smallest tropical fish are often well-suited for nano tanks or small aquariums. The compact body shapes make them ideal choices for hobbyists looking to create a miniature aquatic world.

Popular in community tanks

Most of the smallest tropical fish are peaceful and compatible with a wide range of tank mates. This makes them popular in community tanks, where they can coexist harmoniously with other species.

High light plants

High-light plants require intense light to photosynthesize and promote their growth and flowering. Typically, high-wattage LED lights or specialized plant bulbs are great options. Also, most highlight plants need a longer photoperiod, generally about 8–12 hours. A consistent duration of light simulating a natural daylight cycle is helpful to plant growth.

But sudden exposure to high-intensity light can damage plant leaves. So if your aquarium initially does not provide sufficient light, it’s advisable to gradually acclimate the plants to the high light environment before planting them. Some common highlight plants include Dwarf Hairgrass, Glossostigma elatinoides, Alternanthera reineckii, and various hybrid varieties with red colors.

What does high light mean for plants?

High light, a light level, stands for the intensity of light required for optimal growth of plants. Commonly, high-light plants need a light intensity of more than 40 lumens per liter. Plus, different wavelengths of light, particularly red and blue light, are crucial for various stages of plant development, including leaf expansion, flowering, and fruiting.

Aside from that, high light conditions ensure that light penetrates deep into the plant canopy, reaching the lower leaves and stimulating growth throughout the entire plant. So, the PAR values, measuring the amount of light for photosynthesis, for high-light plants typically should be 120-200μmol/s or higher (or over 80 PAR).

In addition to light requirements, high light plants also demand more maintenance. For example, suitable water parameters, stable water quality, moderate carbon dioxide supplement, adequate oxygen supply, etc.

Best high light aquarium plants

Amazon Sword (Echinodorus species)

Amazon Sword plants are popular for their large, lush green leaves and their ability to tolerate high light levels. They can be used as foreground plants in aquascaping, making great focal points in aquariums.

Vallisneria (Vallisneria species)

Vallisneria, also known as “tape grass” or “eelgrass”, features long and ribbon-like leaves that create a beautiful visual effect when swaying in the water. You can build a vallisneria jungle in your high-tech aquariums.

Rotala (Rotala species)

Rotala is a genus of stem plants that includes various species with different leaf shapes and colors. Many Rotala species thrive in high light and can add vibrant red, pink, or green colors to the aquarium.

Ludwigia (Ludwigia species)

Ludwigia plants are known for their brilliant red, orange, or green foliage. They require high light to maintain their vibrant colors and can be used as background or mid-ground plants.

Cryptocoryne (Cryptocoryne species)

Cryptocoryne plants are popular for their broad, wavy leaves and ability to tolerate a wide range of lighting conditions, including high light. Also, they are often used as foreground or mid-ground plants.

Dwarf Hairgrass (Eleocharis parvula)

Dwarf Hairgrass is a popular carpeting plant that forms a dense, low-growing mat in the aquarium. It requires high light to thrive and can create a lush and grassy appearance.

How to care for high light plants in aquariums

Lighting

Ensure a suitable lighting system in your aquarium. LED lights are excellent choices for high-light setups. Given below are some reference values for keeping high light plants in aquariums.

• Lighting hours: 10–12 hours
• Light intensity: More than 40 lumens per liter
• PAR values: More than 80 PAR (120-200μmol/s, or higher)

CO2 supplementation

High-light plants often benefit from additional carbon dioxide (CO2) supplementation. You can use a CO2 injection system or liquid carbon supplements to provide an optimal CO2 level in the aquarium. Monitor CO2 levels to avoid overdosing, which can harm your fish.

Nutrient supplementation

Regularly provide essential nutrients through liquid fertilizers or root tabs. Look for fertilizers formulated explicitly for aquarium plants, which typically contain nitrogen (N), phosphorus (P), potassium (K), and micronutrients. Just follow the recommended dosages and adjust as needed based on plant growth and algae development.

Water flow and oxygen supply

A moderate water flow rate helps to distribute nutrients and carbon dioxide evenly and prevent the accumulation of waste at the bottom. Besides that, sufficient oxygen is crucial for plant respiration and root health. Plus, if there are fish in a planted aquarium, adding an airstone is better. Because plants will release carbon dioxide at night.

Water quality

Perform regular water changes to remove excess nutrients and maintain stable water parameters. For example, change 15-30 percent of water once each week or once every two weeks. Furthermore, test your water regularly and make adjustments as necessary. In this case, aquarium water test strips will help you a lot and they can monitor 7 crucial water parameters and changes for freshwater and saltwater aquariums.

Algae control

High-light setups can be prone to algae growth. To prevent algae issues, maintain a balance between aquarium lighting, CO2, and nutrient levels. In the face of algae issues, you should address them promptly to prevent them from overshadowing your plants. Actually, you can deal with harmful or unnecessary algae via a bio solution – introducing algae eaters, like Amano shrimp, Chinese grass shrimp, and Cherry shrimp.

Pruning and maintenance

Trim and prune your high-light plants regularly to control their growth and promote bushier and healthier growth forms. Remove any dead or decaying plant material promptly to prevent it from affecting water quality.

The end

To conclude, high-light plants demand longer lighting hours and more intense light intensity. However, preventing algae from thriving in your tank is what you should keep in mind. Because high light gives a chance for algae growth.

For disease prevention, it is generally recommended to quarantine new fish before introducing them to aquariums. The same goes for diseased fish in your tank. Once you find one, you’d better isolate fish to reduce infection risk. In today’s article, we will cover more good isolation in the face of diseased fish in aquariums.

Effective isolation of diseased fish

Whether should you isolate diseased fish

Fish may be infected by bacterial, parasitic, intestinal, or viral diseases. Bacterial disease would cause cross-infections. Parasitic diseases, like worms, can spread throughout the aquarium, which can be considered as contagious. Also, intestinal disease can be caused by feces.

So when should you isolate fish diseased? Following are some pointers for diseased fish isolation.

• Abnormal symptoms: loss of appetite, hard breathing, skin lesions, body color fading, etc.
• Fish are infected by contagious diseases, like parasitic diseases.
• Treatment period: In the case of treatment, especially medication treatment, isolating diseased fish is crucial. It ensures the effectiveness of treatment and reduces the impact on fish and aquarium water.

Requirements for isolation

• Tank size: A separate aquarium with the appropriate size and a great filtration system is necessary. It provides a relatively quiet and low-stress environment.
• Water quality: Keep ideal water parameters and great water quality. Check and monitor water temperature, pH, ammonia, nitrite, and nitrate levels.
• Hiding place: Creating sufficient hiding places, like rocks, caves, or plants, can reduce stress and anxiety in fish.
• Lighting: Appropriate lighting is essential. Some diseased fish require dim light, while others prefer strong light.
• Diet: Some diseased fish may lose desire of appetite. In this case, easily digestible food is a great option.

How to isolate a sick fish

Prepare a quarantine tank

Set up a separate aquarium or quarantine tank specifically designated for the sick fish. Ensure the tank is appropriately sized for the fish and equipped with a filter, heater, and adequate hiding places to reduce stress.

But here comes a question – whether should you use the water from the original tank in the quarantine tank. Actually, if there are a few diseased fish, using partial water (e.g. one-third) from the old tank is viable, which allows sick fish to adapt quickly to the new quarantine tank environment. After 2–3 days of medication treatment, water change is needed. However, in general, the water from the old tank may contain pathogens. So, we commonly use fresh new water with similar water parameters in the quarantine tank, rather than water from the original tank.

Transfer sick fish to the quarantine tank

Move the sick fish to the prepared quarantine tank with the help of a soft fish net. Move slowly and avoid causing unnecessary stress or injury to the fish. If needed, you can gently coax the fish into a container or bag using a transparent tube or cup.

Observe and treat

Keep a close eye on the isolated fish. Monitor its behavior, appetite, and any changes in symptoms. Also, you can consult a veterinarian or experienced fish keeper to diagnose the illness accurately and determine the appropriate treatment.

Avoid cross-infection

Use separate equipment, such as nets and siphons, for the quarantine tank. Clean and disinfect any tools used before returning them to the main tank. Wash your hands thoroughly after handling the sick fish or performing maintenance in the quarantine tank.

Duration of isolation

Keep the sick fish isolated until it has fully recovered or the recommended treatment period is completed. This ensures the fish is healthy and prevents the reintroduction of any potential pathogens to the main aquarium.

Severe bacterial and parasitic fish disease isolation

Set up a quarantine tank

Prepare a separate quarantine tank specifically for isolating diseased fish. Ensure the tank is appropriately sized, equipped with a filtration system, heater, and hiding places, and has no other aquarium inhabitants.

Transfer diseased fish to quarantine tank

You can move the diseased fish with a fish net. Move slowly and gently to minimize stress and potential injury. And be cautious of any sharp objects or decorations that could harm the fish during the transfer.

Observe and diagnose

Monitor the isolated fish closely and note any changes in behavior, physical appearance, or specific symptoms. Research or consult with a veterinarian or knowledgeable fish keeper to identify the specific bacterial or parasitic disease affecting the fish.

Treatments for bacterial diseases

Depending on the diagnosis, administer appropriate medications to treat bacterial diseases. Follow the instructions provided by a veterinarian or reputable sources regarding dosage, duration, and any specific considerations. Some common treatments for bacterial infections include antibiotics and antibacterials.

Treatments for parasitic diseases

If the fish has a parasitic infection, such as ick (white spot disease) or flukes, there are specific treatments available. Follow appropriate medication protocols, which may include antiparasitic medications, salt baths, or temperature adjustments. Be sure to research the specific parasite and recommended treatments for the best results.

Reduce the spread of disease

To prevent the spread of pathogens, it is recommended to use separate equipment, such as nets and siphons, for the quarantine tank. Clean and disinfect any tools used before returning them to the main tank. Wash your hands thoroughly after handling the diseased fish or performing maintenance in the quarantine tank.

Duration of isolation

Keep the diseased fish isolated until it has fully recovered or until the recommended treatment period is completed. This ensures the fish is healthy and prevents the reintroduction of any potential pathogens to the main aquarium.

Wrap-up

To conclude, treating bacterial and parasitic fish diseases can be challenging, and the diseased fish isolation is crucially vital. Before taking any treatments, you’d better quarantine the diseased fish and determine what disease your fish suffer. Then you can take more precise treatment.

Parrot fish profile

Get to know parrot fish

Most parrot fish are known for their vibrant colors and unique body shape. Their bodies are often adorned with various patterns and hues. Also, a beak-like mouth resembling a parrot’s beak gives them the name – parrot fish.

Interestingly, unlike traditional vertebrate teeth, parrot fish teeth are located deep within their throat, rather than fixed in their jaws. Their teeth can be used for scraping and crushing the hard surfaces of their diet. As the outer layers of their teeth wear down from the constant grinding, new layers of teeth are generated to maintain their efficiency.

Besides that, parrot fish can vary in size. For different species, their size ranges from 6 inches to over 3 feet in length. In saltwater tanks, parrot fish prefer shallow and clear water with abundant corals. Plus, they are active and always live in groups. Some species can even change their sex over the lifespan.

Origin of parrot fish

Parrot fish are widely distributed in tropical and subtropical waters around the world. They can be found in the Indo-Pacific region, including the Red Sea, the Indian Ocean, and the Pacific Ocean. They are also present in the Caribbean Sea and the Gulf of Mexico.

Parrot fish breeding

Breeding parrot fish in captivity can be challenging, particularly in the face of complex reproductive behaviors and specific environmental requirements. The following are some general considerations and guidelines for parrot fish breeding.

Tank setup

Provide a spacious tank with ample hiding places, great water filtration, and stable water quality. Parrot fish may require a tank size of at least 75 gallons or larger, depending on the species.

Pairing

It is important to have a compatible male and female parrot fish for breeding. Just introduce them to the breeding tank simultaneously and monitor their behavior closely. It may be necessary to try different pairings to achieve compatibility.

Environmental conditions

Parrot fish breeding often requires specific water parameters. Maintain a stable temperature, typically between 78-82℉(25-28℃), and a pH level ranges from 7.8 to 8.4. Good water quality with regular partial water changes is essential.

Spawning site

Parrot fish typically prefer flat surfaces or vertical structures for spawning. Provide suitable spawning sites, such as flat rocks, PVC pipes, or ceramic tiles, in the breeding tank.

Courtship & Spawning

Parrot fish engage in elaborate courtship displays before spawning. The male may intensify its colors, display aggressive behavior, or construct nests. Once courtship is successful, the female releases eggs and the male fertilizes them externally. The eggs are then attached to the chosen spawning site.

Egg care

After spawning, it is crucial to ensure the eggs remain undisturbed and protected. Some parrot fish species guard and care for their eggs, while others may not. If the parents show signs of aggression towards the eggs, it may be vital to transfer them to a separate incubation tank or use artificial incubation methods.

Fry rearing

Once the eggs hatch, the fry will need specialized care. Provide suitable food for the fry, such as finely crushed flakes, baby brine shrimp, or other small live foods. You should maintain great water quality and monitor their growth and development closely.

What is the portable mean of an air pump

Portable air pumps feature portability and convenience. Most of them are lightweight. In aquariums, portable air pumps generally are small, battery-powered, or rechargeable, making them suitable for fish transportation, outdoor fishing, power outage, etc.

But how do portable air pumps differ from common air pumps? Actually, the two are different in size, power source, and air output.

Differences	Portable air pumps	Common air pumps
Size	1. Compact, lightweight, and easily transportable. 2. Typically, smaller, making them convenient for travel or situations where space is limited.	1. Usually larger. 2. May be designed for stationary use in larger aquarium setups.
Power source	Battery-powered or rechargeable, allowing them to operate without a direct power source.	Common air pumps, on the other hand, are typically powered by an electrical outlet and may require a power cord.
Air output	1. Lower air output. 2. Typically used in smaller tank setups or for temporary purposes.	1. Generally more powerful and capable of providing higher air output. 2. Suitable for larger aquariums or systems that require stronger aeration.

Do small ponds need an air pump

Air pumps for pond aeration

Whether should you add an air pump to small ponds depends on the size of the pond, the density of aquatic pets, the species, and the number of plants, plus the overall balance of the ecosystem. So, what do air pumps do in small ponds?

• Oxygenation

An air pump can help maintain adequate oxygen levels in the water, especially in situations where there is limited circulation or stagnant areas. If your small pond lacks natural water movement, such as from a waterfall or fountain, an air pump can be beneficial in oxygenating the water and supporting fish and other aquatic life.

• Fish and livestock

If your small pond contains fish or other livestock that require higher oxygen levels, an air pump can provide the necessary aeration. Fish, particularly in densely stocked ponds, can deplete oxygen levels through respiration and waste production. An air pump can help prevent oxygen deprivation, especially during warm weather or in ponds with limited plant cover.

• Plants and algae balance

Aquatic plants play a vital role in oxygenating ponds by producing oxygen during photosynthesis. If your small pond has a healthy and well-established plant population, an air pump may be less necessary. The plants can contribute to oxygen levels during the day, while an air pump can be used primarily at night when plants do not photosynthesize and release carbon dioxide.

• Water Quality

An air pump can promote water circulation, which helps prevent stagnant areas and reduces the likelihood of stagnant water issues such as algae blooms or mosquito breeding. If your small pond is prone to poor water quality or has limited water movement, an air pump can aid in maintaining better overall water conditions.

The best air pump for a Koi pond

Take a Koi pond as an example, a portable air pump kit is an excellent option. It is ideal for garden small ponds. The portable air pump kit has a 9 levels adjustable air volume control knob. The airflow can be adjusted according to your preference, max of up to 238GPH or 301GPH. Also, it is equipped with a diverter valve, which can link many devices (like 4 or 6 air stones).

When it comes to power outages

Facing power outages, how to supply oxygen to ensure the well-being of your fish and other aquatic inhabitants?

Battery-powered air pump

A battery-powered air pump is an excellent solution for providing temporary aeration during power outages. These portable pumps can be easily set up and connected to an airstone or diffuser in your aquarium. But make sure to have spare batteries or a fully charged rechargeable battery on hand to power the pump.

Manual aeration

If you don’t have a battery-powered air pump, manual aeration can be a temporary solution. Gently agitate the water surface using a clean container or your hand. This action helps in gas exchange, allowing oxygen to enter the water and carbon dioxide to escape.

Battery-powered inverter

If you have a larger aquarium setup or multiple tanks, using a battery-powered inverter can be an option. It converts DC power from a battery into AC power, allowing you to run your regular air pump or other essential equipment during power outages. This method requires a suitable battery and inverter setup.

Emergency oxygen supplies

Keep emergency oxygen supplies such as oxygen tablets or liquid oxygen additives designed for aquariums. These products can temporarily increase oxygen levels in the water. Follow the instructions provided with the specific product you choose.

Aside from the methods mentioned above, you can also reduce oxygen expenditure by limiting feeding. Moreover, make sure that the temperature in the aquarium remains stable by avoiding direct sunlight or extreme temperature fluctuations. Keep the tank covered to minimize heat loss. Once power is restored, monitor water parameters and consider water changes if necessary.

Wrap-up

To lessen the threats to fish health, it is recommended to prepare a portable air pump for temporary or emergency use. Once facing power outages, apply the portable air pump to tanks with high density and fish requiring higher oxygen levels.
