yea, put everyone in there, because even though they show no signs of it, the ich can still have a fish to go onto before its cycle ends.
im looking into a UV sterilyzer as well. it does help destroy diseases in the tank, which is def. a good thing when it comes to ich. i would also like to get a bigger tank as well.....unfortunatly, my 65 is as big as i can go at the moment, while i still live at home. as soon as i move out, i will probably end up buying a bigger fish tank before i get a couch.
