15 Gallon Showcase

[Mickeybags]

Hi all,
I recently found an abandoned 15 gallon tank. I hosed it down and tested it for leaks. I currently have a 10 gallon community of mostly tetras. I was wondering if there was any single fish, other than a betta, that would be suited for this tank. Since the tank was free I want to keep expenses low except for the stock. I want a basic substrate with some kind of rocks or driftwood to compliment the fish. So does anybody have any recommdantions.

P.S. I already have an aquaclear 30 and hood. All I need is lights and a heater.

A single paradise fish would be nice, but I have heard stories of them becoming extremely aggressive towards other fish.

Or, I know you said you want a single fish, but a big school of celestial pearl danios can be quite the display.
