In the Tank

Ragnheidur (here on ipernity) and I had a little GTG here in Copenhagen yesterday, and we went to the Danish Aquarium with her husband and three sons - we had a good time. Shooting there was a bit tricky; the water not clear, the glass a bit scratched here and there, but a lot of colourful fish.
I used my 50mm 1.4 and started out using 1.4, 1/100 sec and the ISO at 800, then 1.8 and ended up using 2.5m ISO at 500 and 1/125. Very shallow focus, but using a flash is out of the question, it would just "splash" in the glass.
