Greetings,

New here. I picked up 3 bicolor chromis from my LFS - they only had 2 in one tank, so I grabbed one from another.

I've been having issues since I added them, my clown jumped out, and seem to be overall aggressive - some of my corals aren't as active. I only had one clown in the tank previously, had some mishaps after going away on vacation too long, so have slowly been reintroducing fish.

Upon closer inspection, I noticed they looked a bit different. I was hoping for some help in identifying if these are truly the same, or why they look so different.

At this point, I have a pair of the ones on the left, and one of the ones on the right. I am thinking to get rid of the one on the right and see if that calms down the tension.

There are several notable differences with the one on the left:
Overall color
Eye on the back
Eyes
Bicolor

Appreciate any help - curious if they are two different species, or what I can learn about them.

The fish in the first pic seems to be Pomacentrus bankanensis - the Speckled Damselfish - while the fish in the second pic seems to be Pycnochromis margaritifer - the Bicolor Chromis.
