Info
As is often the case with reef perch, the yellow-bellied reef perch comes in different color variations, which are also known geographically. For example, there is a variant from Indonesia that has a yellow-orange belly.
Adult fish live alone or in small groups in lagoons, reef passages, and on the outer reef slopes. They feed on copepods, amphipods, mysids, fish eggs, crustacean larvae, and a small amount of algae.
The eggs are bottom-dwelling and adhere to the substrate. The males guard and aerate the spawn.
Reef perch can be very territorial and quarrelsome towards newly added fish, even larger animals. Keeping them in a small group (sometimes seen in commercial sales tanks) only works with young animals; later on, this is no longer possible. They are quite rough in their behavior!
Otherwise, they are quite stable and not very susceptible to disease. Food intake is usually achieved immediately without any special considerations.
