I've posted a few times before about my fish, DiNozzo. I've had him for 9 months now. Recently he has been looking terrible. Sometimes he will just sit at he bottom of his tank for an hour, not moving at all. He will move when I get his attention, but he just lies so still.
Physically, he looks awful. The first picture is when I first got him, and the rest are ones I took today (10/24/13)
I'm pretty sure he is biting his fins, but I don't know what to do to make him stop, or how to help them grow back. He has also been shedding what I think is his slime coat (flaky bits that look like dead skin to me). I've been doing 80% weekly water changes now and adding Stress Coat conditioner to the water. (Before I used Splendid Betta Complete Water Conditioner)
Does anyone know what is wrong with him? There are days when his energy is fine and he eats normally. Others he doesn't move much at all and will bite at his food, but them spit part of it back up.) He also had a silk plant in his tank but I took it out today so he doesn't make his fins any worse than they already are.
I appreciate any suggestions that people may have. My roommate thinks that he is on his last legs (er, fins). I hope that's not the case. I feel bad if he is in pain and is suffering.
