This is one of the pictures from my recent holiday in the Farnham area, there is a bird park called Birdworld which has a section called Underwater World.
Underwater world was quite interesting, but also very dimly lit, making photography difficult (I didnīt have a tripod with me), I managed to get this one by putting the camera on one of the ledges next to the tank.
This is the uncropped full frame, with slight boost to contrast/saturation and sharpening (I didnīt do the usual infrared R-B colour swap).
(f/5.6, ISO 100, 1.5 sec)
