I have 3 guppies female guppies and 2 are pregnant. I would like to keep some of the babies when they're born while also introducing other types of fish or animals into my aquarium. Currently i have been catching the fry and putting them in a birthing box. I was wondering if african dwarf frogs will eat my fry if i don't catch them in time, and if they will eat my juvenile guppies when i introduce them into the main tank. I would like to get a frog or two if possible and some neon tetras, and maybe a rainbow fish.
