One of the frogs we used to have in our terrarium was an Amazonian Milk Frog. He tolerated the poison frogs, but was best buddies with a green tree frog we had. An accident installing the waterfall system killed the green tree frog. The milk frog honestly never seemed the same after that. Sounds weird, I know. Anywho, here's a great pic of our milk frog that I wish I could take credit for. My wife, Jenn, snapped this really cool photo.
