Yeah, I thought about that and do not plan to do anything right now. Actually, as of last night it is starting to show itself more. Also, I do not plan on adding anymore fish either as I am well aware that I am stocked at the high end and could have issues as current stock matures. Getting the goby was a weak moment with my 4 year old daughter.
Now that we have found it she is quite happy to be able to see it and has appropriately named it "coral"
As for the firefish, it does great! I have read other posts where people state their firefish constantly hides. Mine is out all the time and no one seems to bother it.
I knew the damsel was a little risky when I bought it, but so far no problems. It usually hangs out by the base of an anenome or schools with the chromis from time to time.
For now the tang and pair of maroons seem to share dominance of the tank.
