I have reason to believe I just saw my firefish breed and deposit eggs under a plug of Zoas I recently purchased. They took turns backing into a small hole in my live rock around the Zoas vibrating their tails in the hole. I didn't want to get to close so not to disturb them but It definitely looked like they were spawning in this hole. Does anyone have any information of this occurring before ? I am not prepared or equipped to raise fry so I'm not gonna try but just curious of often this occurs in captivity. Attached are 2 pics of what appeared to be concerned parents. Not really guarding but concerned when other fish got close to the hole.
