I have a mandarin with some white stuff that seemingly is ruining his side fin. Don't know for certain what it is, but I'm leaning toward lymphocystis. Looks kinda puffy like cotton, and the center of the fin is torn or gone. If I could get your input, and what you'd think would be a suitable way to treat this fish, I'd appreciate it. @melypr1985 @Humblefish
I've had this Mandarin since 2011, it's one of the ORA tank-raised fish...
