FBname: Noronha frillfin goby
Comments: Collected from reef crests and bottoms, and shallow tidepools everywhere in Fernando de Noronha and Atol das Rocas, up to 3 m deep. Observed in solitary, pairs or in large groups of up to 20 individuals, often in reef crests with rough waters, and eventually in sheltered sandy bottoms. Feeds mainly on small invertebrates, but also on small fishes.  The eggs are guarded by territorial males, and their agonistic behaviour. Associated with several species of small fishes: blennies <i>Scartella itajobi, Ophioblennius trinitatis, Entomacrodus vomerinus</i>; labrids <i>Malacoctenus</i> sp., <i>Labrisomus kalisherae, Labrisomus conditus</i>; and the goby <i>Coryphopterus glaucofraenum</i> (Ref. 128474).
