I was looking at one of my tanks tonight, and noticed some very small white dots on a couple of my fish, not many maybe 4 dots and 2 or 3 fish have them. I'm not sure if it's ich but if it is I would like to start treating early. I have a bunch of ich meds laying around, so is it ok to do a small dose just in case it is ich, or will it have bad effects if it really isn't ich?
