I have 45 gal tank with tiger barbs, gouramis, and a clown loach. The clown loach has got ich, and I've been medicating the tank for a week and a half now (wish I had a hospital tank right now). The clown loach is definetly feeling better, but he does'nt look any better (still a lot of white spots). The tiger barbs are getting pretty stressed from all the medicating and water changes, and yesterday the ammonia level got pretty high, but is back down now. Should I give the fish a day off or keep going?
