Spawns on the bottom. A male will spawn with more than one female if there is more than one ripe female around. If not, he is satisfied to spawn with one partner and to stay with one female forever (Ref. 12251). Maximum length 25 cm TL (Ref. 2060).
产卵于底部。 如果在附近有超过成熟的母鱼，一只雄鱼将与超过一个母鱼交配。 如果不，他被满意与一交配伴侣与停留永远地有一母鱼.(参考文献 12251) 最大的长度 25 公分TL.(参考文献 2060)
