I got two Guppies a couple of days ago and I think one has fungus. She has this raised, cream-colored bump on her side, and around around it the skin is paler. She has sometimes flicked her side against rocks, and occasionally I notice her fins are clamped. It is still very small and doesn't seem to bother her much at all, but I'm sure something's there. It kind of looks like ich, but bigger and creamy-colored, and there's only one, and from the top you can see it is raised quite a bit. She didn't eat the other day, but I'm almost positive that's because she wasn't settled in yet and was intimidated by my very hungry Platies, and she's as active as usual. Do you think this is fungus? I think I have a medication that will treat fungus...what about salt baths--would one of those help? Unfortunately I don't have a quarintine tank, although I have a bucket big enough for a temporary salt bath, so I'll have to treat the whole tank. She seems fine, but I'm trying not to panic...I'm going to do a water change now. Somebody pleeease answer soon--whether it's fungus, and what to do.
