I wanted to emphasize that if you are looking for a frog to handle in a similar manner as your reptiles, then amphibians are not for you. Amphibians have very sensitive skin and you should treat them just like fish, you do not take them out to play with them. And unlike reptiles, they require exceptionally clean cage furniture and water. If it's not clean enough to put in your mouth, it is not clean enough for amphibians.
Please do some more reading about amphibians, you still have a lot to learn. Since most amphibians are nocturnal, they do not require any ultraviolet light. Just make sure that you are feeding them dusted food items.
Stick around this forum for a while and you will learn a lot! Good luck!
