General information

The Reef Eel, also known as the Sharpnose Eel or Caribbean Sharpnose Eel (Myrichthys breviceps), is a fascinating species for the more advanced marine aquarium. These eels are known for their slender bodies and pointed snouts, which give them their common name. They are nocturnal predators, primarily feeding on small fish and crustaceans in the wild.

In the aquarium trade, they are appreciated for their unique appearance and behavior. However, they require a specialized environment and care to thrive in captivity.

Care

Reef Eels need a large aquarium with a tightly fitting lid to prevent escape, as they are known to be skilled at finding their way out of tanks. The tank should have plenty of live rock and hiding places to mimic their natural habitat and provide a sense of security. Sand or fine substrate is essential for them to burrow and hide.

Feeding can be challenging, as they prefer live foods. Hobbyists should offer a varied diet including live feeder shrimp and small fish to entice them to eat. Over time, some may adapt to frozen or prepared foods.

Reproduction

Breeding of Myrichthys breviceps in the home aquarium is rare and not well-documented. In the wild, they are oviparous, with females laying eggs that are fertilized externally by the male. The larvae are pelagic and drift with the currents until they mature.

Habitat

Reef Eels are found in the Western Atlantic, from North Carolina to Brazil, including the Gulf of Mexico and the Caribbean Sea. They inhabit coral reefs and rocky areas, often hiding in crevices during the day and emerging at night to hunt.
