Is this a terrible fish combo?

I had the same combo in a 24 gal at one time. Worked not too bad. If your going to try the firefish put a top on the tank. They love to carpet surf.

In a 14 I'd only go with 2 out of the 3.

My royal gramma is a real bully now. He was by himself for a while and when I introduced a new goby he beat it up to the point the goby had to be moved. I don't think they are all this aggressive though.
