Small Brackish Tank?

[SuomiBetta]

Are there any brackish water fish species that do well in a 5 gallon tank or would a 10 gallon be necessary for brackish water? Just curious if there's any small space mad aquarium chemists here. Still battling with my water chemistry and right now, my tank has become brackish and basic (water change here I come!)

5 gallon is really small for any fish. Most of the brackish fish that come to mind would not do well in such a small tank.

I figured as much.
