| Biology: |
Usually found in small groups of up to ten individuals; prefers more open areas over sandy bottoms, but always remains near shelter; diet composed mainly of aufwuchs and detritus; sand and mud are also sifted for edible bits, as are the organic layers covering rocks and wood (Ref. 52307). Monogamous (Ref. 81260), pair bonding, ovophilic, biparental mouthbrooder (Ref. 52307, 81260). |
