Good Luck Paul - Rabbitfishes are not 'tangs'. What am I missing...yyaaayyyy Paul you finally added a tang! That gives more credibility to the nonbelievers. I just wish you took and documented taking a tang home with ich and then the fish living happily ever after in your tank. I warn you the blue hippo tangs are dfn cute and do have personality.. I had thought when mine outgrew my tank I would give it away too.... Instead I upgraded to a 180 to keep him b/c I loved him!!
Keep us posted on how he does. Yes feeding tangs black worms dfn gets rid of that spot. It also works with blue spotted puffer fish.
Best of luck with your new fish!
