i have a powdered brown tang he has ich and i've been treating the tank with kick ich and i am on the last treatment day and it looks to be getting worst all the other fish are looking good is it possible that it isnt ich that its something else he is covered head to tail not sure what to do any thoughts thanks

it is possible that it is something other than ich, but it is likely he'd be on deaths door if it was. more likely, kick ich is not a very effective treatment, in my experience. you will be better off setting up a hospital tank treating with either formaline, copper, or hyposalinity.
a pic of the fish can help with a positive ID.
