Ditto. cranwelli almost always loose much or all of their green coloration as they grow. That is what is going on in this case. If you want to count on eventually having a green adult horned frog when your buying a froglet you need to go with ornata. Those almost always end up green, red, or somewhere in between. Most individuals tend more towards the green.
