My new Red eyed tree frog is a light brown color, he was light green yesterday. I think he might be stressd out. I went to a pet shop and bought a 75w infered heat lamp just incase he was too cold. Btw I have had him for 3 days, and he hasn't eaten at all I have small dusted crickets that I tried feeding it, but no luck. I hope he is still getting used to his new habitat! :/. Any tips?
