| Found in sand/rock interface and over sandy patches around the islands, between 13 and 18m; territorial males build spawning bowl from beneath flat rocks; spawning occurs underneath the rock; females and non-territorial males occur in small groups (up to 10 individuals) and feed on plankton in the water column 1-3 m above the bottom (Ref. 57549). |
