Endlers, Lesser killies, Gertrudes rainbow fish, Peacock gudgeon, Goo-obo gudgeon, Pigmy Dwarf Rasbora, cherry shrimp and if you want to go brackish Bumble bee gobies will all work in smaller tanks and I know some people who do keep white clouds quite successfully in 5g.
Some of these fish are harder to find then others and may have to be ordered online, but IMO these are some of the best little fishy jewels you can have in a tank, well worth the time and effort and a nice break from the ever popular betta…which I do still love.
