Các tia vây lưng cứng (tổng cộng) : 14 - 17. Front of body brassy-yellow in the male, with larger pectoral fins than in the female (Ref. 35388).
Adults live solitary or in pairs in weedy, shallow coastal areas (Ref. 4119). Feed on small invertebrates (Ref. 4119). Males build a nest from algae and debris, using kidney excrete as glue. Spawning season is May to June. Females deposit 150 - 200 eggs in the nest and often die shortly afterwards (Ref. 9900). Males care for and defend the nest. Offsprings reach maturity in one year (Ref. 4645).
Males build, guard and aerate the nest where the eggs are deposited (Ref. 205). Also Ref. 53335.
