What carnivorous fish can I add to a 20 gallon tank?

I don’t have a lot of experience with fish tanks, and I’m wondering if I can add a fish to our tank that will feed on small minnows but not be aggressive towards other larger (and possibly smaller) fish. Any idea on what I can add?
A bichir
oscar or pacu but will very very soon outgrow tank an pacu will need 200 gallon and oscar will need 55 gallon
You could try a Leopard Ctenopoma… They are kinda odd in that they look very much like a leaf, and will happily dine on live fish (preferably small Guppies or Minnows, not Goldfish), frozen worms or brine shrimp, and sometimes even pellets. They are fairly docile and will ignore anything that they can’t easily catch and swallow whole.
Another choice would be a smaller species of Dwarf Pike Cichlid, C. regani in particular. This species stays only a few inches in length, and will go after Guppy fry with a vengence.
