A Honeycomb Moray filmed at "Fish Tank" at North Male Atoll in Maldives. This site is a favourite spot to see moray eels. My buddy ono the video is Dive Whit.
The Honeycomb Moray is one of the largest eels and can be up to 2 meters in length. They look mean, but are very gentle as long as you don't provoke them. You should not try to feed them either, as their eyesight is poor, and they may bite off your finger by mistake.
The small fishes swimming around the eel are Cleaner Wrasses. They eat parasites from the skin of the host.
