Inhabits lower reaches of rivers (also found further upstream) in flowing or still water (Ref. 44894). Usually found in flowing streams among aquatic vegetation or branches of submerged trees. Juveniles often occur in swiftly flowing water or brackish estuaries. Tolerant of salinity levels equal to sea water, temperatures up to 35°C and pH 5.0-9.1 (Ref. 44894). Feeds on micro-crustaceans, mosquito larvae and algae. Spawning occurs during the warmer months, when males establish breeding territories and display their dazzling colours to attract a mate. The eggs adhere to rocks, sand or weeds and are guarded and fanned by the male until hatching, which occurs in 10-14 days (Ref. 44894). Smallest vertebrate eggs with max 0.32 mm length. Hatching larvae are about 1mm long.
