First off, congrats on buying a frog. To answer your question, a Fantasy Frog is a hybrid of two species, Ceratophrys Cranwelli(Cranwell's Horned Frog.), and C. Cornuta(Surinam/Amazon Horned Frogs.). They are sterile, and rare, as they are bred in captivity and one parent, the cornuta, is rather rare. I kind of doubt it is a fantasy frog, petco and other stores often mislabel these frogs, but I hope it is a fantasy! I can check if you post some pictures, as can other members. Hope this helps.
