Description of life cycle and mating behavior | Reproduction takes place during high water (Ref. 2756). There is some indication that the species comes to shallower water to breed (Ref. 43507). From 4 breeding fish taken, 3 were from inshore waters and 1 from 40m depth in the open water (Ref. 49805). The nest is a relatively large depression with the shape of a flat dish and proportions relative to the size of the fish (Ref. 51638). A single well formed hole of about 10-15cm in diameter and 10-15cm depth is present nearly in the middle (Ref. 51638). Eggs are laid inside this hole (Ref. 51638). Eggs are white, having a diameter of little more than 1 millimeter (Ref. 45962). Larvae stay in the hole a couple of days after hatching (Ref. 51638). They swim above the nest when disturbed and return to hole after disturbance has stopped (Ref. 51638). |
