Dendrobates tinctorius, also known as Dyeing Dart frog.[link]
Picture taken in the zoo of Wuppertal/Germany with a Sony Alpha 700 and a Sony 16-105 lens, mounted on a Manfrotto 695 monopod.
This picture required a very, very long exposure time due to very dim light. I balanced the camera on the monopod and leaned it against the glass of the terrarium. Then used a self-timer with mirror pre-release to avoid vibrations. Lucky for me, the frog didn't move.
