|Breeding||The fish spawn in the austral spring (August-December). Males guard the eggs (a typical spawn consists of 500-3500 eggs) between their pelvic fins for an unknown period in the nest which the male have constructed among seagrass beds and rocks. The drift weeds found in inshore marine waters, protected inshore marine environments and estuaries act as nursery areas. Cobbler enter these areas during their first year of life and often remain there for long periods.|
