Guppy tank questions

[Cricket1234]

So I am thinking of turning my ten gallon into a small guppy tank/planted tank/aquaponics system. My research said that all guppies breed and breed extremely quickly. Is there an animal species (fish or otherwise) that would eat guppy fry and not bother the adults. And if not, how will I prevent breeding/get rid of the fry? Will they stop breeding when they feel the tank is overstocked? Also, any advice for everything that I am doing will be greatly appreciated. Cya and thanks so much!
