I was away on vacation for a few weeks came home and my fish is sick. He has white/grey on his fins and it seems he has lost some of them. His body is also curled over and he isn't swimming around much, stays in one place.
I have a 10G tank with filter, heater. The temp is always a steady 82. I'm pretty sure he got this from poor water quality.
I did a 75% water change, added some Aquarium salt. I know to keep his water very clean but is there any other advise anyone has?
