Should I get rid of my firefish or my clown goby?

[joseph_cariz]

I wanted a bubble tip anemone to go along with one yellow tang, 2 ocellaris clowns, 1 clown goby, one dwarf flame angelfish, a firefish, and a neon goby in a 55-gallon tank, as well as some mushroom corals, some zoanthids, and some xenae. But since the tank is too small, I'm going to cut a fish.

Should I cut the firefish or the clown goby? Which would get along better? Which grows bigger?
