My royal gramma is currently in QT with copper power. Was doing well until last night, didn’t come out to eat. Pulled him out of the tank this morning to take a look and saw this. He’s not doing so great. Breathing hard, very lethargic. I just finished a 10min hydroplex dip on him and didn’t see anything other than a few scales that fell off. Sort of looks like an injury to me but I can’t think of anything he could have injured himself on. Bacterial infection maybe? Since he’s not eating, should I treat the water column with Kanaplex maybe? You can see in the top down picture fleshy prices hanging off of him.
