Thanks, lots of info, but unfortunately I learned the hard way yesterday. 5 days ago I purchased 3 clown loaches from Petsmart to keep the 2 I already have company. I didn't think they looked as healthy as my fish, but my kids were screaming and i didn't pay close enough attention (pissed at myself). Found my large loach dead at the bottom of my tank, I had it for 3 years. I was looking for possible resons and noticed white dots on the smaller loaches, yeah they have ich. I was able to catch the 3 of them and started treatment on the fish and my tank. I lost 1 of the smaller ones today and it doesn't look so good for the other 2. I don't have another aerated tank to keep them in so they are in a large bowl on my counter. I really don't know what to do to save these guys, any info would be great. Needless to say, i went back to Petsmart and told the fish dude they sold me sick fish and now I need the treatment meds for them and tank. I had to pay for that, apparently you need to bring the fish back to the store to prove illness or death and these guys are too stressed to be transported back and forth. Sucks!

Oh yeah, I agree that's stealing and pretty immoral.
