i had the same problem with my tank........and my fathers reef tank...what we did, was feed the fish 3 times a day up from once a day...and added garlic to the food.we also raised the temp of the tank to 82..this seemed to make the fish less stressed...all 3 of my tangs had it, and just beat it on their own....i believe ich is present in the tank...so when the fish goes in it gets stressed and get it....this same way worked for my dads reef tank...its the only thing that worked for me without using medicine...as i have lost fish in other tanks i had previously to ich....hope it helps you out..
