Ok. Do u have any advice on if my fish will be ok in the smaller tanks until this is all done with? I just wanna get rid of this crap and never see it again.. I'm tired of seeing none for a while then it flares up really really bad then gets a little better than flares up again then goes away.. I don't even do anything to my tanks. The temp stays around the same always.. I do like 30% water changes once a month and about 10% every week or so..that's about all I do.. all my fish are still eating good.. I just don't understand why they flare up with ich out of nowhere all the time.
