Which fish for reducing the number of Guppy fry?

Hello,

I am looking for a small predator that will prey on my Guppy offspring. The aquarium is 80 cm long, i.e. approximately 100 liters, the pH is just below 7. The predator should prefer the fry but leave the adult ones at peace. 

almost all characins sized about 6 cm are suitable, e.g. from the Hyphessobrycon genus. Dwarf cichlids (mainly Apistogramma spp.) will also prey on the fry, some species are also suitable for the aquarium size - however, these fish may themselves multiply so rapidly that the problem "what to do with the babies?" is just switched to another fish species...
