Help! somethings wrong with my yellow TANG!!!!!

It looks like he's getting the crap beat out of him. I assume the regal tang was in there first?

You're kind of in a pickle here. I would recommend you remove that tang and isolate it in its own tank, however, I don't know if the tang would survive the stress of moving and being caught. Hopefully someone else will chime in with something constructive.
