@Jay Hemdal how long do you think I should wait before starting a copper qt for it? The last owner had him for over a year with no reported diseases and I’ve been looking for any telltale signs of ich or flukes but he’s been spotless so far. I would imagine *if* he was carrying ich or anything like that it would have shown itself while he was still recovering from the injuries.
I’m also hesitant on starting anything like copper while he’s still recovering, do you think I could get away with just an observational QT?
I wouldn’t start any copper or prazi until you are certain the fish has resumed feeding.
What other fish are in the tank? I’m concerned that the assessor isn’t feeding because it’s uncomfortable being in the small holding tank. It might feed if let out into the main tank.
You may not need to give this fish a full quarantine. Unless the previous owner added some sick fish to their tank or something right before you got this fish, a year in captivity makes disease much less likely.
