Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 12 - 13; Spine anali: 2; Raggi anali molli: 12 - 13. Color in life white with 3 black bars; has a black area over the outer two-thirds of the tail, which distinguishes it from D. aruanus; pelvic fins black; pectoral fins transparent. Tubed lateral lines scales 16 to 17. Margins of preorbital, suborbital, and preoperculum finely serrated (Ref. 2746). Body depth 1.5-1.7 in SL (Ref. 90102).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Schooling species, adults inhabit sheltered lagoons, harbors and inlets. Also in somewhat open substrates with outcrops of Acropora corals (Ref. 48636). Often associated with small coral heads. Feed on a variety of plankton, including larval shrimps and crabs, algae, ostracods, amphipods, pelagic tunicates, copepods, and fish eggs. 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. 54980; 113699).
