So far I see no other inhabitants with any spots, but I am not sure how to treat, or what to treat with. I am waiting on a 55 gallon to cycle, and was hoping to move everyone in there, but not with an outbreak of Ich. My water parameters have all been stable and ideal, so I am not sure how this all got started unless I got an infected fish to begin with, and the 10 gallon being the only system cycled, there was no where to quarantine. I also am feeling stupid right now for placing part of my biofilter from the outside power filter into the new system to help it cycle, and am fearful I just infected it with Ich. The biofilter chunk was the only thing transferred to the new system.
