I just got this fire eel 2 days ago and he had nothing like this when I got him none of my fish have ich but I treated the whole tank half strength because most of my fish are scaleless and it appears to have gotten worse over night, could it be ammonia burn, or shedding it’s slime coat ? If that’s even possible. I really need some help Nothing else has been picking at him either so it’s not that and suggestions are very much appreciated
