What kind of freshwater fish would be best for a girl tank 2.5?

I have a 2.5 gallon tank (glass container for all the mini-aquarium) and has a filter. i was wondering what kind of fish would be a good fit, I want fish that pleaseing and active. I also like to have more fish. and I have a divider for beta fish.

If you would like t have more fish you need a much larger tank. think of living in a bathroom with some other people. no fun, right? 'll have to get a heater. 7.5watt is a perfect and cost between $ 7 and $ 12. once you have the heater that is pretty limited to a guppy or a Betta … no need for the splitter, the tank is only big enough for a single fish. Sorry. Oh, and please look into the void of gravel, you need to ddo 10% water changes a week, and a gravel vacuum will make it easier for you.
