I'm far from being new to frogs, but I have never had a stressed frog before. She is eating well and moving around, but her color is worrying me. When I got her from the pet store she was light green a little on the pale side, but I thought with a little TLC her color would improve, now she is dark green almost brown. I added some green paper to the back of the tank to make her feel safer. The temperature in the tank is around 75 F (Room temp) and the humidity is about 55%. I used Sphagnum peat moss for a substrate with a drainage layer of Zoo Med Hydro Balls. There are 2 water bowls with fresh filtered water that has also been left in the sun for 2 days. There are plenty of places to hide and climb around in the tank. There are 2 frogs in the tank. My Cope's Gray Tree Frog is doing well in the tank. He sings and eats and acts like a happy little frog. I've been feeding them gutloaded crickets, flightless fruit flies, and small meal worms. I'm planning on getting them a taller/bigger tank with more climbing room soon. Let me know if I forgot to mention anything. Thanks in advance for your help!
