I had 4 new clown loaches in my quarantine tank. I bought them about 3 weeks ago. I've been treating them for ich since they came in, since they had a very minor case of it when I bought them. I raised the temperature to 86 deg. F, I put about 1 tbsp of salt per 10 gal in the tank, and then I proceeded to use Jungle Ich tabs when that didn't work. I had 2 die today, a third is on its back dying right now, and the fourth is certainly on the way out the door. What could I have done differently to save these fish? I do water changes twice a week and I did everything I know of to prevent and eliminate the ich.
