Heteroconger

Heteroconger enigmaticus

Castle & Randall, 1999

Enigma Garden Eel

Not Reef Tank Suitable

Not Suitable for Fish-Only Tank

Range: Indo-West Pacific Ocean: Indonesia and Papua New Guinea.

Size: 17 inches (43 cm)

Natural Environment: Burrows into deep sandy and seagrass areas on shallow inshore coral reefs and is found at depths between 3 to 80 feet (1 – 20 m), and feeds on zooplankton.

General Husbandry: Has an overall dark brown coloration with small white spots. Not collected for the trade.

Taxonomy:

    Order: Anguilliformes

    Suborder: Congroidei

    Family: Congridae

    Subfamily: Heterocongrinae

    Genus: Heteroconger

FYI: Those in this genus are termed ‘Garden Eels’ and reside buried in the sand or mud with only their upper length/head showing while awaiting a tasty meal to come close enough to be captured and eaten without going too far their burrow. They require at a minimum, for the shortest species, very deep fine sandbeds, e.g., 8 inches (20 cm), more if a large species, and tankmates large enough not to be eaten.

Best displayed in tall ‘special species’ type aquariums/public aquarium displays.

Minimum decor is ideal, as they prefer wide-open areas to see incoming food possibilities, and to be maintained in small groups/colonies.

Basically unsuitable for the average home reef or fish-only aquarium as they require very deep substrates to encompass their entire body.
