Hi, I have a powder blue tang in quarantine (retired 55gal, hence the rocks etc). Currently ramping up copper power. Just finished a bout of General cure (2 doses) plus Furan-2 (3 doses) and Kanaplex (3 doses) for a bacterial infection prior to starting the copper power. Powder blue eating well, acting nicely. But has a lumpy body. Don’t think it’s parasites since I just did all the dosing mentioned. Curious if anybody else has seen this before. He’s fast so the videos stink. TIA.
