Territorial males are found at depths of 11-23 m and build bowers by excavating sand from beneath rocks; females and non-territorial males feed in the open water column 1-3 m above the bottom and on benthic invertebrates; mouth-brooding females occur solitarily and stay close to the substrate (Ref. 57549).
