Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 15; Εδρικές άκανθες: 2; Μαλακές εδρικές ακτίνες: 14 - 15.
Body shape (shape guide): fusiform / normal; Cross section: oval.
Adults occur in small patch reefs of shallow lagoons, with algae or seagrass habitats. The stomach of several specimens examined contained mainly algae and detritus mixed with sand grains (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 113699).
