Fish for a 24 gallon

[Josh23]

I'm going barebottom so I don't think I can keep gobies, what other fish do well with barebottom tanks...

I'm not crazy about O clowns, they don't swim around a lot I want a lot of movement. What else would you recommend?

So far I have:
- firefish
- longnose hawk
- royal grama (or should I not add one due to aggression)

not sure on these:
- tomato clown (change to O clown)
- gobies? (not good in barebottom tanks)

Any other ideas
