Very cute frog you have there

. S/he is definitely a cranwelli. A very nice one.
It's true, pet stores very often mislabel them, sometimes to our advantage. Fantasy frogs are a mix of a cornuta and a cranwelli, as mentioned. They are neat frogs too. They are, however, sterile and cannot produce viable offspring. The females coloring tend to fade some. I have two fantasies, a male and a female. They have higher peaked horns and the common pattern on their backs.
I'll take some pictures if you'd like, but they are currently happily sleeping under their substrate
