Possible Parasite?

[narcist21]

This afternoon I was checking out my tank and noticed that my Mimic has a pretty good size white almost fleshy chunk on his right side visible. I didn't notice it yesterday so I'm wondering if he got into it with somebody else or is it parasite related?

Basic Info-
Tank size- 120
Age of tank- 6 months (sand/rock has been established for two years)
Lighting- 440W VHO
Salinity- 1.024
Water temperature- 78-80
Nitrites- 0
Nitrates- 0
Calcium - 460
Magnesium-? (haven't checked in a while)
pH-8.0
Dosing anything?- nope
Any recent changes to tank- Last addition was two wrasse from my 24 that was sold two weeks ago, nothing for a month before that.
Inhabitants (fish)- Yellow tang, Mimic, Tomato Clown, Two osc. clowns, hawkfish, spotted dragonet, and a midas blenny.

A couple of pics. He moves too fast to get a good shot.

Any ideas?

Thanks,

If it's an issue with nutrition and not a parasite, you may want to look into vitamin supplementation (soaking nori in a vitamin mix).
I'm guessing it's a physical injury, but it's hard to tell with the pics. Maybe with a clearer pic, someone else will be able to reply with a diagnosis.
Maybe the Mimic didn't like the wrasses (large, small? what kind?) and they got in a scuffle?

The wrasses are a couple of 1 1/2" Flashers that stay far away from the bigger the fish. I'll see if I can't get any clearer pics today.

yellow tank kicked it's butt. two tangs basic same shape, one is going to boss tang and I would say the yellow won.
