A few pictures of a real sick Tang

This Tang is suffering from the post infections as a result of a nutritional deficiency and is now probably infected with parasitic protozoa. The blotches appear to indicate so.

Aggressive treatment is necessary to cure the fish of the parasitic infection with anti-protozoal medication, and then it should receive a high vegetable diet and preferably a high dosage vitamin C treatment for at leat 30 days. Even then, it is unlikely that the skin will heal to a degree where the skin damage disappears completely.
