1- I have a Koi angel fish that has been sick for about 3 weeks now. The fish has lost its left fin and has like a growth on it. It swims upside down erratically like it cannot control where it’s going. It was already doing that before it lost the fin. I’m not sure it’s eating. It tries to get to the surface when I put food in, but I don’t see it eat. The belly area is a little pinkish. I saw the other angels picking on him before he started to look sick, but he’s been in the hospital tank for a couple of weeks and is not improving. I have treated the tank with Melafix.
2~I don’t know my tank parameters. The fish has been moved to a 10 gallon hospital tank.
3~ The fish is currently in a 10 gallon hospital tank that I just set up for this situation with a used filter. The fish was transferred from my 60 gallon community tank. The 60 gallon has been up and running for about 5 years.
4~The 60 gal. has a Sunsun canister and a Fluval HOB filter.
5~The 60 gal. currently has 4 angel fish (about 2.5 inches from mouth to tail) and 3 sterbai cories (adult about 1.75 inches)
6~I do a 50% water change once a week. I do not vacuum the gravel.
7- I’ve had the fish for about 8 months.
8~I have not added anything new to the tank.
9- I am feeding them Omega One flakes, bloodworms, pellets.
