i had same problem at first i bought garlic drops and dipped food plus one drop each day he is doing great now.. how big is he ?? any signs of disease ?? send picture.. they are very tame but if he is getting skinny you need move quick ...my yello wtang same thing but once he bit the tang no more trouble but tang could stress fish. my yellow tang is trouble with any new fish..still bugging my kole tang...is it male or female?? im looking for small one do you know who might have one.
hes doing perfectly fine now
its been months after he started eating...he doesnt bother anybody and noone bothers him thank god..
well i have a pair but it was the male that wasnt eating ...hes about 3 1/2in
maximum reef aquatics have them.. male and female..for about 35 dollars i think..great deal
