Like 5 days ago i started noticing small white dots on my gold severum and oscar which was moved to a quarantine tank 2 days before due to damage on his skin. Oscar soon got full of white dots and i treated him with paraguard for 5 days and he’s completely fine now. I’ve been treating my main tank with my 2 severums but they’re still not better. They are full of white spots and some white things are coming out of their skin. Their poop is fine so it’s not internal. My red severum stays at the bottom of the tank but eats normal somewhat. My gold severum flashes himself to rocks, filter, and glass. He just stays on the top of the tank near the heater most of the time. i bumped the temp to 83 degrees and i’ve been treating with paraguard. I don’t know what else to do. They’ve been like this for like a week now and red is lethargic and the gold just stays on one spot in the top. Any tips?
