New Fish - Hope it Works out

Hello All:

I bought a new fish yesterday. I researched it and I visited it at the LFS about 5 times for about two weeks to make sure it looked healthy to me.

My current set-up:

92 Gallon corner
23 gallon sump
UV sterilizer
PhosBan reactor with NPX BioPellets
Urchin skimmer
Bio balls (I know they are not loved by all)

I already had:
2 Ocellaris clowns
1 banded gobie
3 blue/green reef chromis
1 red flame angel (heretofore the boss of the tank)

Yesterday I bought a yellow chromis. The LFS was marketing it as a sunshine chromis - but it is definitely just a yellow chromis (chromis analis I believe).

The gobie at first was pissed off. He did not like a fish as big as him in there. He was very territorial and pushy. That is not his common behavior. So I shut the lights off in the tank. Today it seems better. The gobie doesn't like the yellow chromis - but he is not overtly nasty. The yellow chromis is eating very well.

Does anybody keep these or have any opinions?

Pictures coming next...
