The Banded Moray Eel, Echidna polyzona, also known as the Barred Moray Eel is a challenging species to keep and should only be cared for by experienced aquarists. Additionally, the Banded Moray is best kept in a tank of at least 75 gallons with plenty of live rock, a thick sandy substrate (3-4 inches), and a tightly sealed lid to prevent escapes.
