You can keep one in a 10, but if you have the funds I would reccomend getting the largest tank (in the nano range) that you can afford.) What I mean is that a 10 would work for a firefish but a 20 would make your life a bit easier as far as tank parameters, top offs (yes you will be wishing you got the 20 just because of the to offs), and possibly even live stock choice (not much different but you have room for an extra fish to go with the firefish in a 20 as opposed to the 10~ I would be hesitant to add anything else to 10, not saying it cant be done (as lordroad is a testimant to) but you have to be on top of everything in the tank)
