Hello everyone! My son who is 7 years old has 2 dumpy frogs. He has had them for 3 weeks. We love watching them eat, climb and sit in their water dish.
We have a problem with one right now though

The smaller one is turning dark grey (this one is ushually a nice green color) Im feeling that its stressed not sure why though we havent changed the tank or anything recently but did get our crickets from a differant place? any suggestions on what to do?.

thank you!
Elizabeth
