Try looking for the gobies section.
Some excellent fish that can go in a 10 gallon tank are:
- Neon Gobies
- Clown Gobies
- Redhead Goby
- Two Spot Goby(which are extremely awesome looking fish)
- Yellow Watchman Goby( Famous watchman goby, but needs a fairly deep sandbed)
- Hi Fin Banded Goby
And there are tons others, but you should research, "Nano Fish". You will get lots of hits, and find some amazing fish.
