Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Male defends a defined territory, within which a female resides. On the day prior to spawning, female pushes her snout into the sandy bottom repeatedly and removes small stones and pieces of coral at several sites. Adhesive eggs are deposited on the sandy bottoms or in a small cavity of the reef covered with sand. Female fans the eggs and defends the nest, while male patrols around female (Ref. 8603). Females are territorial, solely tending and guarding the eggs (Ref. 116451). Males exhibit polygyny (Ref. 116451).
