How many fish in a ten gallon?

[AdamsB]

Is upgrading to a 20 gallon an option? If so you'd have more option stock wise. I had 2 clowns in an uncovered 20 gallon. Everything was fine for a few weeks then noticed some aggression. Didn't think much of it being pretty new to salt water. Woke up one day to clown jerky on the carpet. Now I have a perc and black perc in a 90 gallon and they get along fabulously.

If its not an option then I would keep only a firefly and get a gobie of some sort (research first as no all are suitable) or even a cardinal. I find live aquaria Is a decent database and even if the description isn't what you want then read the testimonials people write.
