Alright guys, its definitely nipping. I woke up this morning and hes got CHUNKS out of his tail and its just in tatters :'(. Ive never actually caught him at it, but it appears that hes doing it at night. Ill get some bettafix this weekend... hes currently getting salt baths whenever I get the chance. I dont know if maybe its Lucifer on the other side of the tank thats stressing him out? Did some rotations and have Giovanni by himself and Lucifer and Alejandro in the split... I dont think so, but is there anything I can do to discourage this behavior? It makes me sick to see him like this!
