Tangs with Red Marks

[nauticac4]

I have 3 tangs a powdered brown, tenneti, carribean. They all have small red marks on them all over their bodies almost like something made little tiny cuts all over them. They are very small and brownish in color. I cannot get a picture with the camera I have. Any suggestions?

They are in a reef and I have not added anything for about 3-4 weeks. I do a waterchange once a month about 20%.

yea I saw that and the pictures on the third page looked nothing like this. I really don't think I could fish them out of the tank either to put them in hypo or a dip.

It's probably bacterial. Try Melafix a natural antibiotic and garlic soaked food.
