New aquisition - spotted mandarin goby

Trouble in paradise?

Over the weekend I added a spotted mandarin goby to the tank. See the picture here on the side.

I haven't noticed him eating much of anything. Several evenings I have douched him shrimp brine but he doesn't seem to eat it, nor does he touch cyclopeeze or even Rod's food.

I know that these guys are hard to keep , but I didn't expect a real issue. So, I'm going to keep doing what I was doing and maybe he will adjust before it's too late.

There were some scuffles at the introduction of the fish in the tank but he/she seems accepted in the tank community as the fish leave him alone.
