So today I noticed something odd in my freshwater aquarium. A lot of my fish have this odd look to them, kind of like some sort of rot or fungus maybe, however not quite. Some of their bodies look as if they’re covered in lint or something, it’s hard to explain. I’ll try to see if I can get any decent photos to share. It’s weird though cause it just showed up today, and it’s not on all my fish, but enough to have me concerned. It’s only visible when they go directly under the light, for a second I was worried it was ick, but it after looking at it a bit longer it’s become clear that’s not what I’m looking at. What’s odd is that one fish with it is acting somewhat lethargic and moving a lot less, while one will not stop swimming in circles. Just over and over again. It kind of looks like they’re covered in little fibers of cotton or something.. but all the pictures I’ve seen of fungus don’t resemble it either. I guess my question is what could it be? And can I use Maracyn or Lifeguard on it? (I have both.) The only problem is, I also have 2 Snails in the tank, 1 nerite and 1 black racer snail. There’s also a peacock eel in there.. so I’m not sure what meds are safe and what aren’t. Please help, I need to do something! Also, unfortunately I don’t have a hospital tank at the moment, so anything I use has to treat everyone.
