Moray eels in the aquarium

Moray eels live in the bottom layer of water, so to speak, at the bottom. During the day, they sit in crevices of rocks or coral, with their heads out and usually moving them from side to side, looking for passing prey. At night, Moray eels get out of shelters to hunt. They usually feed on fish, but they also attack crustaceans and octopuses, which they catch from ambush, darting out of their hiding places and grabbing a passing victim.
