Use a species-only tank of at least 30 gallons (113 liters) with a height of at least 16 inches (40 cm) for optimal water circulation.
Float the bag in the tank for 10 minutes, then gradually add tank water to the bag over 30 minutes to equalize temperature and salinity.
Keep temperature between 22–26°C (72–79°F), salinity at 1.020–1.025, and pH between 8.1 and 8.4.
Feed live or frozen small crustaceans like mysis shrimp, brine shrimp, and copepods multiple times daily.
Choose peaceful, slow-moving species; avoid aggressive or fast feeders to prevent competition for food.
A minimum of 30 gallons (113 liters) is recommended for a pair; larger tanks are preferred for groups.
Maintain a temperature of 22–26°C (72–79°F), salinity of 1.020–1.025, and pH between 8.1 and 8.4.
They primarily consume live or frozen small crustaceans like mysis shrimp, brine shrimp, and copepods.
They should be housed with peaceful, slow-moving tankmates and are best kept in species-only tanks to prevent stress.
