In a 30 gallon
36¼ × 12⅝ × 16¾ in outsideHow to keep orandas
Orandas are fancy goldfish with a raspberry-like hood (the wen) over the head and a split, flowing tail. Keep two or more in a 30 gallon or larger tank at 64 to 74 °F with strong but gentle filtration, and only with other slow fancy goldfish. Thirty gallons for two follows the rule of 20 gallons for the first goldfish and 10 for each one after; more room keeps the water cleaner.
Diet: Omnivore: sinking goldfish pellets, blanched peas and greens, frozen foods. Fish food types compared · how often to feed.
Where they swim: All levels.

What an oranda tank needs
A tank of 30 US gallons or more (such as the 30 gallon) with a cover, and the equipment below. Orandas are comfortable at room temperature, so a heater is optional in a normal home.

Common oranda problems
- In some fish the hood grows over the eyes; a vet who treats fish can trim it safely.
- Floating upside down or trouble staying level is common in round-bodied goldfish; feed sinking food, keep the water clean, and see a vet if it does not improve.
Test the water first whenever fish look unwell: see what your readings mean, then match the symptom. For disease, a vet who treats fish can diagnose it and advise treatment.
