Eels available to the marine aquarium enthusiast belong to three distinct families. Moray Eels belong to the family Muraenidae. Garden and Conger Eels belong to the family Heterocongridae. Snake and Worm Eels belong to the family Ophichthidae. The most common genera of Eels available include: Echidna, Rhinomuraena, Gymnothorax, Myrichthys, and Taenioconger. Most Eels reach a size of 24 to 36 inches in an aquarium. In the wild, the largest species reaches a length of over 12 feet. Eels are found in tropical and temperate waters around the world. They are most commonly associated with coral reefs, rocky areas, or sandy flats.

Moray Eels are equipped with razor sharp teeth used to eat prey and ward off predators. Other types of Eels use holes and crevices within the reef to easily elude predators. As the name suggests, Garden Eels live in large colonies in sandy flats. Moray and Snake Eels live a more solitary life taking refuge in small holes within the reef.

Eels feed mostly on fish and crustaceans, and most species adjust well to life in an aquarium and are very hardy inhabitants. A larger aquarium with adequate hiding places and a well-sealed lid is essential for maintaining Eels in an aquarium; they are expert escape artists.

In the majority of these fish, no recognizable characteristics differentiate males from females. It is extremely difficult to breed Eels in an aquarium.

They are generally compatible with: Large Angelfish, Boxfish, Groupers, Grunts & Sweetlips, Lionfish & Scorpionfish, Puffers and Tangs & Surgeons.
