And by the way...yes! Those Killifish are super cool! How many could I have in a 5 gallon?

Those killies- probably 1 male and 3 females would work well. They're not shy fish, so you'd probably see them a lot.

The problem with small fish is that many of the common ones are schooling fish- which means a proper group of them requires a larger aquarium. If you want to get a heater you could get a betta- which are really interesting fish. They're quite hardy and obviously easy to find. Dwarf puffers would work in a 5 gallon, if you're up for it. Unfortunately they're very sensitive fish and picky eaters, so they might not be the best ones to try right away, but it's a thought.

IMHO I would get some killies, as they're much more rare and exotic than a betta, but also kinda hard to kill. I'm quite killifish obsessed right now though so I'm bias.
