Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生

Males defend small territories at the spawning sites and construct nests made of plant materials. They dig shallow depressions or clean spawnng substrate, at 2-3 m depth. They guard nests until larvae emerge. Spawns in pairs. Eggs hatch in 5 days (Ref. 59043).
