what is wrong with my yellow tang

[crcoachm]

Got home today and feed my fish. And my yellow tang has red on him. Kinda of streaking looking. Not covered just kinda of spotchy.
He did eat. Feed them Omega food.
Seems to be acting ok.
Any Ideas?:help:

ok I just checked for ammonia.
I use tetra testing with drops.
It says it takes 20 minutes for result.
As of now the color in the tube is yellow, but does not match up yet to the test kit, lite green to blue.
What would be a common cause of ammonia spike?

over feeding could be a cause
I will do search thank you
Any chance he would survive, I am guessing water changes now, Right?:notsure:

I believe I read in the disease forum that red streaks can be a bacterial infection of some kind. I advise you post there and get the opinion of the pros.
