| Description of life cycle and mating behavior | The spawning places are over gravel in moving water (Ref. 205). "Males are territorial and excavate shallow depressions about 50 cm in diameter and 5-10 cm deep in sand or gravel, or among exposed plant roots on which eggs are deposited, usually in turbid water and at 1-3 m depth. Spawn in pairs, at dawn or night. The female remains over the nest while the male circles rapidly around, at about 1 meter from the nest. Then male takes a vertical orientation and both swim around swiftly, and eggs and sperm are released, The female leaves the nest after all eggs are released. The male defends the nest and fans the eggs with his pectorals. Females spawn once a year, laying all the eggs at one time (Ref. 88075). Feeding larvae are positively phototactic and feed on pelagic organisms after they leave the nest for open water" (Ref. 59043). |
