Common name: Debelius' Reef Lobster

General Information

The Debelius' Reef Lobster (Enoplometopus debelius) is a striking addition to any marine aquarium, known for its vibrant purple coloration and bright orange or red legs and claws. This small reef lobster is a favorite among aquarists due to its manageable size and captivating appearance. Native to the Indo-Pacific region, it inhabits rocky crevices and coral reefs, where it spends much of its time hiding during the day and foraging at night.

This species is named after Helmut Debelius, a renowned marine biologist and underwater photographer. Its unique coloration and reclusive behavior make it a fascinating choice for hobbyists looking to add diversity to their tank. However, it is important to note that this lobster is best suited for aquariums with plenty of hiding spots and a peaceful community of tank mates.

Care

The Debelius' Reef Lobster is moderately easy to care for, provided its specific needs are met. It requires a well-established aquarium with stable water parameters and plenty of live rock to create hiding places. This species is nocturnal and will spend most of the day hidden, emerging at night to forage for food. A tank with subdued lighting or areas of shade will help it feel more secure.

While generally peaceful, this lobster can be territorial, especially in smaller tanks. It is best kept as a single specimen unless the aquarium is large enough to accommodate multiple individuals with ample space to establish territories. Care should also be taken when housing it with small, slow-moving fish or invertebrates, as it may view them as potential prey.

Diet and Feeding

In the wild, Enoplometopus debelius is an opportunistic omnivore, feeding on detritus, small invertebrates, and organic matter. In captivity, it will readily accept a variety of foods, including sinking pellets, frozen shrimp, and chopped seafood. Supplementing its diet with algae wafers or vegetable matter can help ensure balanced nutrition.

Feed this lobster once or twice a day, preferably during the evening or night when it is most active. Overfeeding should be avoided to maintain water quality and prevent waste buildup in the tank.

Behavior and Compatibility

The Debelius' Reef Lobster is a solitary and nocturnal species, spending much of its time hidden in caves or under rocks. It is generally peaceful but can become territorial if its space is encroached upon. Providing ample hiding spots and a spacious tank can help reduce aggression.

This species is considered reef-safe with caution. While it does not typically harm corals, it may prey on small fish, shrimp, or other invertebrates if they venture too close. It is best housed with larger, fast-moving fish and robust invertebrates that can coexist without conflict.

Health and Common Issues

With proper care, the Debelius' Reef Lobster can live for several years in captivity. Maintaining stable water parameters and a clean environment is crucial for its health. Regular water changes and monitoring for ammonia, nitrite, and nitrate levels will help prevent stress and disease.

When selecting a specimen, look for a lobster with vibrant coloration, intact claws, and active behavior. Avoid individuals with damaged appendages or signs of lethargy, as these may indicate poor health.

Molting is a natural process for this species, during which it sheds its exoskeleton to grow. During this time, the lobster may hide more than usual and appear vulnerable. Ensure it has a safe, undisturbed hiding place during molting to reduce stress and prevent predation by tank mates.

Habitat

The Debelius' Reef Lobster is native to the Indo-Pacific region, including areas such as the Philippines, Indonesia, and the Great Barrier Reef. It is typically found in rocky crevices and coral reefs at depths ranging from 10 to 30 meters (35 to 100 feet).

In captivity, replicating its natural habitat is essential for its well-being. Provide a tank with plenty of live rock, caves, and overhangs to create hiding spots. A sandy substrate and moderate water flow will mimic its natural environment, while stable water parameters will ensure its health and longevity.
