Queen angel being cut or something else?

[motomatt86]

Hey,

My queen angel and blue hippo tang are being aggressive and I have noticed that there is a slice in his lower body and some other marks... Should I treat with antibiotics to prevent a problem or let them heal naturally. Is there an antibiotic that does not discolor tank or mess with skimmer?

it almost looks like there are scales falling out. one site looks like a slice and another site is towards the rear but is on both sides exactly in the same spot on both side... those do not look like cuts.... what could it be?

here are some pics...

its the two spots... 1st is on the bottom center of yellow stripe and second is about 2 inches back above the blue stripe where it looks discolored...
Thanks
Matt

Looks like some scales got nicked and are sticking out. They should heal without issue, assuming very good water quality.

The aggression is your bigger concern. What are your plans to deal with it?

agree with SDguy...
Just keep you water par stable and keep your fish healthy...

What size of tank do you have?
They can get pretty aggressive if they are in a small tank...
