Predator Fish for my 30G Tank?

I'm looking to stock my new 30G tank. Here is my ideal fish(that I dont expect to exist)
Ideal Fish:
Will do fine in a 30G, maybe even be able to have a pair.
Can eat other fish, like small/medium guppies to small goldfishautolinker.com autolinking image.
Either be very active or be able to have a medium sized school of 5 or so that it wont attack.

So now that i'm done being unrealistic here's what i'd like. I want something that can feed off an occasional guppy/mealworm treat as I raise mealworms for fishing bait anyways and I have a 10G breeder tank producing guppies. It doesn't really matter if i'm only able to keep just this one fish as I understand a 30G tank isn't going to be necessarily ideal.

Thanks in advance

check out exodins aka buck tooth tetras. U could keep about 15 or so in the tank. They are pretty bad @$$ and are like lil pirahnahs that stay about 3"

Would they be able to eat a medium sized guppy when they reach adult size?

A sunfish would do fine by itself in a 30 gallon. They would defintely eat guppies and mealworms, and doesnt require a heater.

Current Tank Setups:
5.5 Gallon Planted Tank
30 Gallon Long

Leopard cptenapoma.

max size 5-6 inches isually, and they are ambush predators.

Amazing little fish that use the motion of surrounding plants to blend in and ambush smaller fish.
Thier mouths are much larger than they seem. They hold thier own with african cichlids, yet also do fine with docile fish that are to big to eat.

150G, 1 Silver arowanna 10", 1 leopard ctenapoma 6", 1 Distichodus Sexfasciatus 9.5", 1 florida Gar 14" 1Tiger Shovel nose catfish 8" 1 featherfin pleco 11" 2 silver dollars, 2 tank bred angelfish, 1 clown knife 18", 1 Jaguar hybrid syntadonis 8" 1 synodonis decorus 7" 1 Datanoid 4", 6 african cichlids, venustus, Jack dempsey, Geophegus, yellow labidichromis, electric blue labidichromis, jewel cichlid, all but the jewel are at 4 to 6inches."
