I spent most of my time looking and reading, so didn't end up taking many pictures. As such, here are one or two that turned out alright.
This one looks good in colour, but I like the fronds and shapes of the anenome, and you don't often see clownfish in black and white.
It turns out I am horrible at photographing jellyfish.
This guy looked bored, which is a shame because they're incredibly intelligent creatures.
Clownfish in colour, because they are bright orange after all.
