Waldo is sssoooooooooo cute. I cant wait for my little GTFroglets to get bigger and chubbier. I have them in my old fish tank that came with the standard hood. There was an opening in the back of the hood for the heater, filter, air tubes, etc. that I covered with a screen. Across the top of the tank are two straps that run front to back, I'm quessing to ensure the hood wouldn't fall in. My froglets perch up there and since it is black I can always tell where they've been. Right now they're are too small, too many and my camera is unable to capture the details of their little chublet bodies for good pics. When I can I'll be happy to post them...I can't wait!
