Common name: bullseye reef lobster

General information

The Holthuis' Reef Lobster, scientifically known as Enoplometopus holthuisi, is a strikingly colored crustacean that adds both beauty and intrigue to a saltwater aquarium. This species is named after the Dutch carcinologist Lipke Holthuis in recognition of his contributions to the study of lobsters. It is characterized by its vibrant coloration, typically a mix of purple, red, and orange hues, with white spots along its body and claws.

Care

Holthuis' Reef Lobsters are nocturnal and tend to hide during the day, making them an interesting addition to a reef tank with plenty of live rock for shelter. They are generally peaceful but may show aggression towards conspecifics or similar-sized crustaceans. A varied diet of meaty foods such as frozen mysis shrimp, brine shrimp, and chopped seafood is essential for their well-being.

Reproduction

In captivity, breeding Enoplometopus holthuisi is quite rare. In the wild, females carry the fertilized eggs under their abdomen until they hatch into planktonic larvae. These larvae go through several stages before settling to the bottom and developing into juvenile lobsters.

Symbiosis

While not known for any specific symbiotic relationships, Holthuis' Reef Lobsters can contribute to the tank's ecosystem by scavenging for detritus and uneaten food, thus helping to maintain water quality.

Habitat

Enoplometopus holthuisi is found in the Indo-Pacific region, from the shallow waters of coral reefs to depths where light penetration is minimal. They prefer complex reef structures with ample hiding places to retreat during daylight hours.
