i would recommend to get UVB for pixie, in a wild they live in open thus gets a lot of sun light and while it is not proven if UVB needed or not for african bullfrogs, but I'd say you better have it, 2.0 is sufficient, provided that a frog has where to hide if he chooses to.

also I'd say aim for 50/50 water/substrate set up, and get yourself ready for big poops and aggressive eating, if you think your pacman eats a lot just wait for when you have pixie lol

anyhow will be waiting for pics
