Tank compatibility[edit]

The Rock bass has an relatively peaceful disposition and can be easily out-competed in a tank of aggressors, i.e. those related Centrarchids with genus Lepomis.


Live foods work best. Worms, grubs, and insects are readily accepted. Rock bass have a large mouth to body size ratio and will feed on smaller fishes given the opportunity. They should avoid being fed feeder fish however.

Feeding regime[edit]

Depending on chosen diet, one to two times a day.

Environment specifics[edit]

Rock bass need freshwater of a temperate temperature. They prefer a demersal lifestyle.


Being fairly shy, they like to be able to hide. They need cracks and crevices and will often use these hiding areas to stage ambushes from.


The Rock bass is a rather un-remarkable fish. They resemble a typical sunfish in body shape and size, however they possess a large mouth and will always have a red iris around the pupil of the eye. They are brown-to-green in colour.
