Sorry about the pictures. It keeps swimming around and these are the best I can get with my phone while it is moving. Just like the title says, this is my first sick fish I am am having trouble finding exactly what is wrong.
I added this captive bred orchid dottyback into my tank on Jan 11, 2021. It seemed to be doing well, but about 3 days ago I noticed it looked like this. I haven’t noticed it get any worse, or better. It still is very active. It and swims around and eats fine. No other fish seem to bother it, or have the same problem yet. I haven’t had any lucky googling trying to figure out what is wrong. This is my first tank/first sick fish so I am not sure what to do.
The fin at the back almost makes me think another fish attacked it, but I have never noticed any aggression towards it and it doesn't appear to be afraid or hiding. The gills make me think maybe something else is wrong?
Any links or suggestions on what to do would be greatly appreciated. If there is anything I can do to help it recover, or at least prevent any other fish from getting sick I would like to do it.
Below is all the details of my tank, if any of them help. Thanks again for any advice.
Tank info:
200 gal IM EXT

I have also added a few pods and used ARC coralline algae
I have 4 T5 bulbs that have been going for ~1m now in a T5/LED hybrid fixture. I have not added any of the LED lights yet. I plan to add 4 XR15’s when its time to add coral.
