I have 2 catfishes about 10 cm long in 50 l tank together with another fish. There was a white spot explosion and I was using "JBL Punktol" for treatment, lost 5 neons, but all other fish are fine except catfish - there were no white spots on them, but it looks like this medicine are doing harm to them. They lost their whiskers and partly flukes, and their skin seems to be peeling. Now i keep them in seperate tank and do not use Punktol there.
So, my question is - are there any chances for them to get well? If no, then maybe I should fastly end up hassle for them? What should i do to get them better?
