Speechless, really.
It was...unbelievable. Really. It's hard to find words to describe that. At first you got in, it was just empty, there's just that serene silence, that... Turn around, and all of a sudden, this whole space is filled with fish, just frenetic, fast-moving fish just going crazy. From then on in, it was just absolutely intense. You don't know which is up or down or side. Your whole frame of reference goes off. And finally, the net was the one static point, wasn't it? At the start of the dive, you feel like the net is something to keep away from, but by the end of the dive the net is the only thing you can use as a frame of reference and everything else is just moving, and it's very disorientating.
