Aquarium overstocking

[Zoaelite]

I have a feeling that a few people will agree with me when I say stay away from the chromis. They are fun fish in a larger tank but in a 29 cube they tend to be pretty nasty, plus they get fairly large. How about 3 fire fish, they are amazing in groups (although a little timid off the bat) and are much less territorial. Throw a large snail shell in there and there set.

3 chromis OR 1 chromis with 1 firefish.

Will either option be too much of an overstocking?? which one would be a better fit in terms of compatibility?
