Bullseye Reef Lobster (Enoplometopus holthuisi) – Complete Care Guide

General Information

The Enoplometopus holthuisi, commonly known as the Bullseye Reef Lobster, is a striking addition to marine aquariums. With its orange coloration and purple accents, this crustacean is both a visual delight and a fascinating species to observe. Native to the Indo-Pacific region, it is often found hiding in crevices and under rocks in coral reefs. Its nocturnal habits and bold coloration make it a unique choice for aquarists looking to add diversity to their tanks.

Although not as commonly seen in the trade as some other invertebrates, the Bullseye Reef Lobster is highly sought after for its aesthetic appeal and relatively manageable care requirements. Its hardy nature and adaptability make it suitable for intermediate to advanced hobbyists.

Care

The Bullseye Reef Lobster requires a well-established aquarium with plenty of live rock to provide hiding spots and mimic its natural reef habitat. It is a nocturnal species, so it will spend most of the day hiding and become more active during the night. A tank with a secure lid is essential, as these lobsters are known for their climbing abilities and may attempt to escape.

While generally hardy, the Bullseye Reef Lobster is sensitive to sudden changes in water parameters. Stable salinity, temperature, and pH levels are crucial for its well-being. It is also important to ensure that the tank is free of aggressive tank mates that may harass or harm the lobster.

Diet and Feeding

In the wild, the Bullseye Reef Lobster is an opportunistic feeder, consuming a diet of detritus, small invertebrates, and organic matter. In captivity, it will readily accept a variety of foods, including sinking pellets, frozen shrimp, and other meaty marine foods. Supplementing its diet with occasional offerings of algae-based foods can help ensure balanced nutrition.

Feed the Bullseye Reef Lobster every other day, providing only as much food as it can consume within a few minutes. Overfeeding can lead to water quality issues, so it is important to monitor its intake and adjust portions accordingly.

Behavior and Compatibility

The Bullseye Reef Lobster is semi-aggressive and territorial, particularly towards other crustaceans and similarly sized tank mates. It is best kept as the sole lobster in the tank to avoid conflicts. While it generally leaves fish and corals alone, caution is advised when housing it with small, slow-moving fish or delicate invertebrates, as it may view them as potential prey.

Despite its territorial nature, the Bullseye Reef Lobster can coexist with a variety of reef-safe fish and invertebrates, provided the tank is large enough to accommodate its need for space and hiding spots. Introducing it to a tank with established territories may reduce aggression.

Health and Common Issues

The Bullseye Reef Lobster is a hardy species but can be susceptible to stress and disease if water quality is not maintained. Regular water changes and monitoring of parameters are essential to prevent issues such as shell disease or molting complications.

When selecting a Bullseye Reef Lobster, look for individuals with intact appendages and vibrant coloration. Avoid specimens that appear lethargic or have visible signs of damage or disease.

Habitat

In the wild, the Bullseye Reef Lobster is found in coral reefs and rocky environments throughout the Indo-Pacific region. It prefers areas with plenty of crevices and overhangs, where it can hide during the day and emerge at night to forage. Replicating this environment in captivity with live rock and a sandy substrate will help it feel secure and exhibit natural behaviors.
