Take proper care of a goldfish on a minimum budget
Tank size & Tank decoration
Though the minimum tank size of oranda goldfish is 20 gallons. However, the larger, the better. A large tank provides more swimming space and helps maintain stable water conditions.
Moreover, tank decorations with sharp edges should be avoided, which will harm fish. The available and excellent choices can be smooth rocks, stones, or ceramic ornaments. While the aquarium decors also provide hiding places for fish. Additionally, live aquatic plants can be another option. They are also beneficial to maintain great water quality by absorbing nitrates.
Keep consistent water temp
Oranda goldfish are cold-water fish, and they can tolerate a wide range of temperatures. Though they can thrive in cooler water temp, maintaining consistent water temp within the appropriate range is necessary. Commonly, oranda goldfish prefer a water temperature ranging from 65℉ to 75℉ (18℃ to 24℃). If the water temp is too high, you can cool it with the help of an aquarium chiller.
Diet & Feeding
A balanced and varied diet consists of high-quality flakes or pellets rich in protein, fats, and carbohydrates, as well as bloodworms, brine shrimp, daphnia, or other fresh and frozen foods, plus occasional fresh vegetables (e.g. spinach, peas, lettuce).
But, you should avoid overfeeding. Just feed oranda fish small portions multiple times each day, and offer the portion they can consume within a few minutes. For example, 2–3 minutes.
Additionally, never feed dry foods exclusively. While pellets and flakes are convenient, dry foods can sometimes cause digestive issues. Hence, incorporating moist foods is necessary, which helps promote proper digestion.
Tank mates
Incompatible tank mates in a tank can be a mess. If you want to introduce tank mates, it is vital to ensure adequate space. The compatible tank mates for oranda fish include:
- Other Goldfish Varieties: Orandas can be kept with other peaceful and similar-sized goldfish varieties, such as Ryukins, Fantails, or Black Moors.
- Common Plecos: Common Plecos (Hypostomus plecostomus) can be compatible with Oranda goldfish as they are generally peaceful and are bottom-dwelling fish.
- White Cloud Mountain Minnows: White Cloud Mountain Minnows (Tanichthys albonubes) are small and peaceful fish. They are active swimmers and can occupy the upper areas of the aquarium.
- Snails: Certain species of snails can be suitable tank mates for Oranda goldfish, such as Mystery Snails or Nerite Snails. They are peaceful, slow-moving, and can help with algae control in the tank.
- Shrimp: Some aquarium shrimp, such as Amano shrimp or Cherry shrimp, can be compatible with Oranda goldfish. However, keep in mind that Orandas tend to eat small invertebrates, so there is a risk that the shrimp could be seen as food.

Maintain great tank conditions
- Do regular water changes
Commonly, it is feasible to perform partial water changes once every week or every two weeks. During the water change process, you can supply a water changer, which helps to save lots of time and energy.
- Monitor aquarium water
Typically, you can test the aquarium water after water changes. Aquarium water test strips can monitor seven crucial water parameters, including PH, hardness, total alkalinity, carbonate root, nitrate, nitrite, and free chlorine levels.
- Filtering and aerating your tank
To keep clean aquariums and sufficient oxygen levels, adding an aquarium filter, air stone, or air pump would be helpful. As an aquarium filter can remove excess waste and toxic substances, such as ammonia, nitrite, and nitrate. While an air stone or air pump can oxygenate the aquarium water.
- Tank and aquarium equipment cleaning
Generally, regular cleaning is vital. For example, once each month. You can clean the tank glass and decorations using a soft cloth or sponge. Also, to ensure everything is functioning properly, it is better to regularly check equipment, like a light or air pump.
How many goldfish are in a 30-gallon aquarium
A 30-gallon aquarium can be used temporarily for young Oranda goldfish, but it is not considered suitable for long-term housing of Oranda goldfish. Adult oranda goldfish can grow up to 8–12 inches (20-31 cm). It means that as they grow up, you will need to upgrade to a large tank. Also, oranda goldfish produce a significant amount of waste, which can quickly lead to water quality issues in a smaller tank. Thus, to keep fish healthy, a large tank is better.
In addition to aquariums, what about ponds? Can oranda goldfish live in ponds? Exactly, the answer is positive. Oranda goldfish can live in a pond, provided certain conditions are met. For instance, pond size, pond precautions, temperament, water quality, feeding, etc. Also, ponds can provide a more natural and spacious environment for Oranda goldfish, allowing them to exhibit their natural behaviors and grow to their full potential.
