Just got back from Cuba, found a fish that needs an ID

Wow, that was fast

He was such an amazing fish to watch, I must have followed him for 10 or 15 minutes.

Thanks for the help.

Saw a bunch of other cool stuff there too, a bunch of lionfish, some sort of puffer (looked like a valentini), tons of urchins, a couple of small squid, a barracuda, angels, and lots of big tangs.
