Pez, my beautiful HM guy, seems to be biting his tail. He was fine until he spotted another guy next to his tank and that flipped him out apparently. There was also a silk plant that had sharp plastic parts on it that I had to remove from his tank, thinking that might be it since he liked to hide behind it. He also use to let himself be sucked up to the filter (before I put nylon over it) and just hang out there. So I put the nylon on it thinking THAT might be the problem with his tail.
Can you guys look at these pictures and tell me what you think it could be - biting or ripping? If it is biting due to the other fish, I don't have the room to put him in his own tank. I will have to see if someone can adopt him :-/ (or return him to the store?). I'd hate to have to do that :(
Sorry about the weird colors - i tried with the flash on and off.
his tail has always been ruffly and lacy, but not ripped and chunks missing like it is now.
