Wow, fantastic tank! Almost as nice as when I was diving on a reef and seeing such while I was part of the 'aquarium stock' as well ... however, that time I came face to face with a really giant Moray Eel - this monster was over ten feet long (only part of his body out of the reef and his vertical size was a foot and a half! Never heard that those things could get anywhere that large!) Lucky for me, he was only begging for a handout, not looking at me as said desired morsel ... . Three other divers saw and approached as well – all confirmed its size … as did the drive master back on the boat (he already knew about it just didn't think to tell us before hand.) Still hard to believe its vast size.
