Breeding Biology
Few
detailed reports on spawning or general behaviour. Spawning probably
occurs in May, although this will vary according to geographic location.
During the spawning period, the male’s head darkens, and it selects a
spawning site under a ledge or rock. Courtship behaviour occurs with the
female entering the nest and depositing her eggs. The male remains to
guard the nest and circulates current over the eggs by fanning his
pectoral fins. Spawning may occur when water temperature reaches 100C. |
