I was wondering if anyone had any experience with bella gobies? I've had one for a little over 2 months in my 30 gallon was one of the first fish added allong with a orchid dottyback and 2 clowns about 3 weeks later. Everything was fine for about a month but in the last week or so the bella goby has been acting agressive towards anything it sees. No fin nipping or anything yet but im worried it may kill something eventually. I can find very little information on this fish but everything says it should be peacful with everything except other gobies or sand dwelling fish.
I'm thinking that my tank may be to small for him despite every source i read says it should be fine. Ive added a picture of the tank.

so maybe just posturing. Problem with mine was that it showered all lower level corals with a layer of sand which became a maintenance nightmare.
