Hi,
My husband and I are relatively new to this, we have a 150 gallon tank, running a year. We added a small spotted tang about 2 months ago and then added a flame hawkfish a week ago. The tang now has ripped fins and white  'scrape' marks on his scales with paler areas. We think he is either being attacked - although no evidence during the day - or got slightly caught in the wavemaker. Any thoughts or advice? He is eating fine despite this. We have the following fish in the tank; 6 line wrasse (although been in the tank for a year and not attacked anything other than another wrasse we had to move on), 2 ocellaris, blue damsel, goby, yellow tang, regal tang and the spotted tang and red hawkfish.

Would appreciate any advice as hard to catch either and dont want to stress the little one out any more.

Looks like it's being bullied. The damsel, tangs and wrasse are all candidates. You've added a normally more peaceful fish after more aggressive fish, the opposite of general advise. The issue there is, the more aggressive fish then claim territory and defend it from anything them deep as less aggressive than them.

Keep an eye on the tank at night if that's when it's happening, figure out which fish is the bully and sump it for a few days. You can then reintroduce it.

Or, if no sump, try moving the rocks about. It changes the territory and everything can claim a new spot.

Hawkfish are known to be a bit aggressive,

Those are grazes on his skin. My tang had that, and there wasn't a single aggressive fish in the tank.
I would increase his algae and greens intake, frozen meaty foods reduce their colouration and it's not good for them
