So i am having tank issues with corals im my tank but i thought it was isolated to just corals. Last night I noticed a brown spot at the base of the fins on my yellow tang this morning i noticed the fins are deteriorating any suggestions???
Has anyone been picking at the tang? In my experience with tangs, fins like that usually comes from something stressing it out but every fish is different. Have you tested your water lately?
The brown spot is blood. Either someone is beating him up or he has a bad bacterial infection. If you don't see someone attacking him then he needs treatment in a treatment tank with heavy antibiotics.

++1. It would be best for the tang and your other fish to get him out and set up a hospital tank with copper in it. Looks like fin rot to me
Here is a little more info he one of my oldest fish no new inhabitants in several months. I have never seen him picked on by the other fish. He acts totally normal and still has a good appetite.
did full water tests last week slightly high on phosphates= .16 and nitrates 10 will test again today but losing several corals as well not sure if it correlates or not.
Several weeks ago I did a treatment with Cheamiclean but have done 2 water changes of over 20% since
