I have a yellow tang in an established reef tank. Recently I have noticed a slight reddish blotchyness on him. He’s eating like a pig doesn’t seem to be bothered at all. From what I’ve read it could possibly be a bacterial infection. I just ordered Kenaplex. I plan on dosing food with focus and kanaplex. I have read dosing through food isnt the best because you don’t know what does the fish is getting. It’s really my I my option. There’s absolutely no chance whatsoever of catching him and getting him into a qt for treatment. Is treating the food the best alternative? I feed both frozen and pellets. I started adding vitamins to the food as well and I also picked up some live black worms.
