I have no idea what's wrong with my fish. His dorsal fin looks like it's turning white and now has a tear in it. It's just a patch of the fin that turned white, not the whole fin. I noticed it yesterday and immediately went out and bought aquarium salt, removed everything from his tank, changed the water and added aquarium salt. For now he is in 1 gallon with nothing but a heater and thermometer.
I don't know what happened. I checked everything that was in the tank, nothing with sharp edges. The only thing I could think of was the wisteria I added to the tank the other day. I bought the plant from petsmart in the tube. When I got it home I opened it up and the plant was half rotted. I was going to bring it back but I couldn't find the receipt, so I thought it would be ok if I trimmed off the rotted parts and put the plant in his tank. Maybe it made him sick? I have no idea. I don't even know what he is sick with.
Please help, I'm really worried.
