Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found mainly around oceanic islands and near reefs along the continental coasts (Ref. 9276). Found in schools in seaward reefs above drop-offs (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on zooplanktons (Ref. 89972).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Males establish a territory for spawning and parental care but not for feeding (Ref. 116451). Only females tend the eggs but both parents keep guard (Ref. 116451).
