Care notes

A tank of at least 100 liters is required, with a mature system and a large population of live copepods. Parameters: temperature 24-28°C, pH 8.1-8.4, salinity 1.020-1.025. A rocky setup with plenty of hiding places is essential. Diet must consist of live prey (copepods, brine shrimp); it often refuses prepared foods. It is compatible with peaceful fish but may be bullied by aggressive species. Warning: do not add to a new tank, as it will starve.
