This was one of many great night dives in Curacao and we found it particularly rewarding due to the amount of octopus out on the reef most of which were sporting a fabulous array of colours, all pictures were taken with an OM-D E-M5 in Nauticam housing.

Nice shots. I always enjoy night dives for the reasons that you mention, the array of different critters that are out and about.
