<<Take a look in Freshwater Fishes of Victoria, Gary Backhouse may have
included some breeding observations if they had been spawned>>
No notes on captive spawning but Arenigobius bifrenatus spawns in nature in spring and summer. Males defend a territory and adhesive eggs are attached to a stone and guarded by him. Maximum age about 4 years. The biological notes are excellent - thanks fo
r reminding me to find my copy.
