O.k so I got some tiger barbs, one of which had ich. I didn't notice this until he was in my tank (I don't have a second tank at the moment So I couldn't quarantine). Anyway long story short My tank has ich and After searching everywhere I got a lfs to order the Red tailed shark I wanted (last fish I plan on adding to my aquarium) and they get it tomorrow. Do I buy the fish and just treat the tank with him in there or do I wait until I get rid of the ich to get him? I really bugged the store to get them to order it and it would be kind of lame to them if i didn't buy it not to mention they might all be sold before I get my tank ich-free. Would It be o.k to get him? PS- My Heater doesn't bring my tank passed 72-74 So I cant really raise the temperature and I have a pictus catfish in the tank So are there any special precautions I should take when treating this ich?
