Scientific name: Uropterygius concolor Rüppell, 1838

General information

The Muraenid Eel, also known as the Brown Moray or Brown Reef Eel, is a species of moray eel found in coral reef environments. Uropterygius concolor is known for its uniform brown coloration, which provides excellent camouflage against the reef. This eel is a nocturnal predator, spending its days hidden in crevices and emerging at night to hunt for prey.

Care

Brown Moray Eels require a specialized aquarium setup due to their size and natural behaviors. They need a large tank with plenty of rockwork and hiding places to mimic their natural habitat. These eels are escape artists, so a tightly fitting lid is essential to prevent them from leaving the tank. They are carnivorous and should be fed a varied diet of meaty foods such as fish, squid, and shrimp.

Reproduction

Little is known about the reproductive habits of Uropterygius concolor in the wild or in captivity. Moray eels generally lay eggs, and the larvae, known as leptocephali, are pelagic for an extended period before settling on the reef.

Habitat

Uropterygius concolor is found in the Indo-Pacific region, from the Red Sea and East Africa to the Society Islands, north to the Ryukyu Islands, and south to New Caledonia. They are typically found in shallow waters, often hiding within the reef structure.
