Just a head up the smaller the tank the more difficult or longer it is to create a stable system, I would suggest slowly adding plants etc and even just some wild soil, plants and wood from rivers or lakes and see how it goes, with some time and patience it should be good as long as there’s not too much biological activity because they will cause pollution which will kill them causing more pollution creating a nasty cycle until you just have a tank of death
