Thats why I wanna trade the firefish.

the clowns in that sized tank will get mean and will bite you , fire fish will fight to the death if they arnt a mated pair as well .

I don't think so about the clownfish.The firefish aren't being mean to each other so I think they are a pair.

If the firefish weren't a pair one would be dead by now.

Are you positive about that:question:

If you had to ask how many fish you can have in a 10G, AFTER adding them, this leads me to think you could use a bit more experience/research in the hobby which leads me back the my original question.

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.

NO upgrading is not a option.The fish seem to be happy not breathing hard.
