Washy once bubbled...
If it's the same eel that I've seen there (a large green moray), which I thought was called Eekie (or something) then please be careful. I saw a DM almost loose his finger and had a stay in hospital courtesy of an eel at the sandbar.
The rays are v.friendly though - watch out for "Darth Vader" a playful ray who is jet black in colour....
The eel I'm referring to lives in 16 ft. of water and won't come out in the daylight unless there is some chow in his face.
