Powder Blue tang bumpy. not ich bumpy

So my powder blue does have ich, yesterday was covered in white spots today he is not, I know ich has a life cylce, He is scratching on the rocks a bit

but his body is bumpy, the bumps are the same color as him, he looks lumpy

I have been soaking his food in garlic, I cannot seem to get him to eat anytihng onther then sheets of nori and gracilaria, or algae off the rocks.

Any idea what the bumps could be? I wasnt going to pull him because I think it will be too stressful, but I dont thinkg Im going to have a choice soon if he pops up with anything else. 2 months in qt and he had nothering:-[

 

just keep him eating...whatever he wants/will eat...the bumps could be from all the scratching.

 

Any suggestions on what else to get him to eat, he will only eat the nori and gracilaria, cant get him to take anything else,


Should I offer him large quantitied of the gracilaria and nor??

 

give him as much as he will eat...but dont let it get rotten in the tank...i know a few people that feed tangs broccoli because its very rich in vitamins...
