Blue Tang Scratching On Rocks

[mcquillian]

My Blue Tang seems to be rubbing against the Rocks in my tank. All of my other fish seem to be fine. Is something wrong? What do you suggest that I do? Thank you for your time in advance. 8O

he may have the early stages of ich or he may just have an ich.

my yellow tang did that for awhile when i first got him. I thought it might be the early stages of ich, but wasnt positive. SO i did a freshwater dip with him for about 30 seconds just to be sure and hopefully kill any ich if there was on him. Well i guess I can never actually tell if he did or not cause i could not pysically see any ich but he did fine after that he scratched a couple more times after that but is still fine months later. P.S. if you decide to do a freshwater dip make sure it is the same pH and temp. of the tank so you dont add anyMORE stress than he will already have.
