Description of life cycle and mating behavior Males defend small territories in the spawning sites and construct nests made of plant materials. They dig shallow depressions or clean spawning substrate such as willow (Salix) and roots. Males guard the nests until larvae emerge. Spawns in pairs. Eggs hatch in 2-3 days. Larvae live in the nest until yolk sac is absorbed for 2-4 (Ref. 59043). Eggs are surrounded by a mucous and adherent wrapping. Incubation lasts about 50 hours at 24°C. Egg size 3 mm, larval length at hatching 8.5 mm (Ref. 26211).
