What fish can live in still tanks?

the only fish that i can think of is a Betta (Siamese fighting fish) because they are usually kept in a 1 gallon fish tank although i don't advise that i would suggest around 4 gallons or more but from what i read they prefer to be without a filter because their long fins tend to pull them with the current and its okay to be in still water because they live in salt patties in the wild.
