Can be a threat to small fish

This spicies might be a threat to smaller fishes.

Can be a threat towards small crustaceans

This species can be a threat towards small crustaceans, e.g. small shrimp.

Escape specialist

Morays can easily escape from aquaria, they can even move loose lids and glass covers without problems.

Feeding of Moray eels

Morays should be fed a large meal every 3-4 days, as they otherwise can harm themselves by over eating.
If one has problems with getting the Morays to eat frozen fish or crustaceans, try moving the food in front of the fish with a tweezer. 

Do note, that the food must be varied and raw/fresh, whole shrimps or smelt (small fish) for example.

It can take a week before they start feeding in the aquarium, but this is not a problem.
Try feeding them live fish or shrimp if the Morays iare not eating frozen foods after a week. 

Keep in mind
Live food

There is a greater chance of success with this species if one can supply a living feed to allow it to adapt to the tank.

Rearranges rocks and sand

This species has a habit of rearranging rocks and sand.

Make sure rocks are placed securely on the substrate, so they cannot toppled over.

Fastidious feeder

These fish eat exceptionally slowly and can be very selective feeders.

It can therefore be problematic to provide it with a sufficient and varied diet, in an aquarium with other, faster feeding species.

Hiding places

This species needs good hiding places, for example, between live rocks.

Hermaphroditic

This species can change gender from female to male.

When a male is needed, a female changes sex and takes on the role.

Descriptions and further reading
Family description (Muraenidae)

Moray eels (Muraenidae) are predatory fish that will most commonly live off fish or crustaceans. 

To avoid overfeeding, the Moray must only be fed every 3-4 days, but may then also have a large meal.

They may dig up the substrate or move loose objects in the aquarium, so fastening the rocks and corals to the tank is a good idea.
Moray eels can easily escape from the tank if not tightly closed. They can lift lids and glass covers, do not underestimate their escape ability.

It is important that the Moray can, with its full length, hide between the rocks.

There are a few Moray eels which are suitable for reef aquaria, but the bigger species can only live in large tanks with other big fish.

Many Morays have a slightly poisonous bite, although it is not normally dangerous for people. One must not underestimate the strength of their bite however.
