This tiny frog spends its whole life living in small pools of water found in leaves. It comes from The Amazon Basin. It was photographed in The Blue Planet Aquarium at Ellesmere Port, not far from Chester.
Jan and I went in search of these at Colchester zoo but didn't find them. This is avery nice shot, he looks like he's got his head on one side listening to something. You got a well-deserved high score Steve.
