Guppy Breeding Population

Hello!
So I recently just got a 20 gallon tank with 2 female guppies and 1 male guppy. Are there any recommendations on fish that may eat the guppy fry to keep the population in check? I will also have about 5 shrimp and a school of cory catfish in there. Would tetra’s eat the fry?
The tank has all necessary materials. Lots of floor space and live plants, moss balls and plenty of hiding spaces!

Look at profiles on apistogramma. They are small and would eat the babies, but i don't know how well they would do alone and whether 20g would be enough space for them if you had a school of corys.
A betta may or may not work. Not enough bioload to worry about, but may still want more space or be too aggressive for the guppies.

You could get ghost shrimp, they are big enough to eat the babies when they are rely small...

I just started breeding guppies and so far I am about 7 months in and not overstocked yet. My females are weird and will literally eat all her fry one by one as she births them. I have a heavily planted tank including floaters and somehow I still don't end up with much fry unless I catch them and put them in a breeder box. So far my guppies themselves and my black neon tetras have kept the population in check, especially if I skip a feeding or two I always notice more fry missing. Corydoras won't touch the fry. A fast agile fish would be good at eating the fry.

Dont feed your fish for 3 or 4 days after they give birth and you'll probably have no fry left.

I agree with everything but the shrimp. Whisker shrimp may eat the fry but not ghosts. And whiskers may try to hurt other fish too so not the best idea.

Leopard/zebra danios are exceptionally good at eating guppy fry

Ok. I just know that some of the species that are sold under the "ghost shrimp" label have pretty decent sized claws/pincers, so i thought maybe that species would be able to catch a few newborns. It was honestly the only other thing I could think of that would fit in a 20g and not kill everything LOL

Yup, that would be whisker shrimp! Only thing is that they sometimes tear other larger fishes tails so might not be great unless you only have a few.
