Help! What is wrong with my Royal Gramma

[newreeferontheblock]

Have had this gramma for 2 weeks - no strange behavior (well, not strange for a Gramma :) ), seems to be eating fine and very active. However I have noticed discoloration in the middle of his body. Under blue light it looks a bit like a grey sheen, but under white light it is a bit more of a mix of grey/brown. Attaching some pictures, but he refuses to keep still...

EDIT: Video as well:

Pictures are not super clear, but the two common causes for this would be flukes or tankmate aggression. Have you seen the gramma do any flashing/scratching? What other fish are in with it? Is it eating o.k.?

Eating fine - I feed a mix of frozen Mysis and pellets depending on the day and goes after both. Additionally, I see it pecking on pods throughout the day.

No overt flashing, however I did notice last night it get close (side by side) with the PJ Cardinal (like it was trying to cuddle as weird as that sounds) who is its only other tank mate. Not really aggressive at all (will occasionally chase the gramma away from a spot but never continues the pursuit)

Added a video here, possibly better than the pics:

Is there a similar discoloration on its left side? Aside from the paleness, the fish looks fine in the video. Gramma are notorious for turning pale in captivity, but that would show up on both sides.

It is on both sides... could be a false alarm then.

Just monitor it for now - any new symptoms could be a sign of something more serious.
