Biology     Glossary (e.g. epibenthic)

Occur at temperatures ranging from 16.0-40.0 °C (Ref. 2). Feed actively in the evening. Young O. alcalicus grahami eat eggs as they are shed by the female, and much of the time and energy of the territorial male is occupied in driving them off. Feed on invertebrates, at the surface (Ref. 2).
