Common name: cleaner shrimp

General information

The Golden Coral Shrimp, Lysmata grabhami, is a strikingly colored marine invertebrate that is highly sought after in the reefkeeping hobby. This species is known for its bright red and white banded body, which not only adds a splash of color to the aquarium but also serves a functional role in the reef ecosystem. They are often confused with their close relative, the Lysmata amboinensis, but can be distinguished by the number of white bands and the absence of a long white stripe on the back.

Care

Lysmata grabhami is a hardy species that adapts well to life in captivity. They require a well-established aquarium with plenty of live rock and hiding places. These shrimps are sensitive to changes in water quality, so maintaining stable water parameters is crucial. They are omnivorous and will accept a variety of foods, including frozen and flake foods, but they particularly enjoy feeding on parasites and dead tissue from other tank inhabitants, which makes them valuable members of the clean-up crew.

Reproduction

An interesting aspect of Lysmata grabhami is their reproductive strategy. They are protandric simultaneous hermaphrodites, meaning they start life as males and develop female reproductive organs as they mature. They can self-fertilize, but typically prefer cross-fertilization with another shrimp. In the aquarium, they can reproduce, providing a fascinating opportunity for hobbyists to observe their life cycle.

Symbiosis

Golden Coral Shrimps are known for their symbiotic relationship with reef fish, offering a cleaning service by removing parasites and dead skin. This mutualistic interaction not only benefits the fish but also provides the shrimp with a steady food source. They are not host-specific and will clean a variety of fish species, making them an excellent addition to a community tank.

Habitat

In the wild, Lysmata grabhami is found in the Eastern Atlantic, from the coast of West Africa to the Azores. They inhabit coral reefs and rocky substrates, often seen cleaning fish at cleaning stations. They are typically found at depths where light is sufficient to support the growth of benthic algae and corals.
