Ok i have a striped raphael catfish that is super nocturnal i hardly see him due to his nature. Today i got glimpse of him thinking he was dead because he was bloated and laying in door to cave. I saw him move so he is alive, i took out cave, the fish is very active and appears healthy, but his stomach is super fat and black tint on the inside, what could it be? i dropped three algae waffers in there this evening before leaving for dinner and mall, now he is fat, a gourmai is anorexic but all other fish appear normal and fine. Is it possible the raphael is female and pregnant? how long can they hold eggs or what not if it is female? there is only one in tank so would have to be from LFS but the fish is close to two and a half months in my tank now. Just boggled because seems healthy but super fat in stomach area.
