So i recently picked up a pair of clowns for my 32 gallon biocube and have noticed that they both have ich. They seem to behave and eat normally but they have lots of noticeable spots on them. I do not have the space or budget to setup a QT tank to treat them so i was wondering what the most effective way to treat it directly in the tank would be without harming my corals or inverts. Please let me know any suggestions.
