Description of life cycle and mating behavior Spawning occurs in small groups (a larger female and two smaller males or two females and up to six males) that engage in chasing, circular swimming, and fin erection. The group then ascends to shallow water, females roll on their side, and eggs and sperm are released. Deposition of eggs usually occurs in a single night (Ref. 1998). Larvae pelagic (Ref. 7471).
