Description of life cycle and mating behavior Oviparous. Spawning takes place under nest stones (Ref. 37679). Egg masses are guarded by males (Ref. 37679). The male hovers around the female to initiate the courting phase, fully extending all his fins, opening his mouth, showing his gills, and slowly fanning his caudal fin. The body and fins of the male turn black, in contrast to the reddish orange margins of the dorsal and caudal fins. The female doesn't show any color change (Ref. 37679).
