Common name: scarlet cleaner shrimp

General information

The Fire Shrimp, scientifically known as Lysmata debelius, is a striking species of cleaner shrimp that is highly sought after in the reefkeeping hobby. Its vibrant red coloration, accented with white spots and long white antennae, make it a standout addition to any marine aquarium. Originating from the Indo-Pacific region, this shrimp is not only admired for its beauty but also for its beneficial cleaning services, as it helps to remove parasites and dead tissue from fish.

Care

Lysmata debelius requires a well-established aquarium with plenty of live rock and hiding places to feel secure. They are sensitive to changes in water quality, so maintaining stable parameters is crucial. A varied diet including frozen and dried foods specifically designed for marine invertebrates, as well as offering them the opportunity to clean fish, will keep them healthy and active.

Reproduction

Fire Shrimp are protandric simultaneous hermaphrodites, meaning they possess both male and female reproductive organs at the same time. In the aquarium, they can reproduce with a partner, and hobbyists may occasionally find their shrimp carrying a clutch of greenish eggs under their abdomen. Raising the larvae to adulthood, however, is quite challenging due to their complex life cycle and specific planktonic feeding requirements.

Symbiosis

While not involved in the classic symbiotic relationships seen with some fish and anemones, Fire Shrimp do offer a symbiotic cleaning service to fish. This mutualistic interaction benefits both parties: the shrimp gains a meal from the parasites and dead skin it removes, and the fish receive a health check and grooming session.

Habitat

Lysmata debelius is found in the tropical waters of the Indo-Pacific, from the Red Sea to the western Pacific. They typically inhabit coral reefs and rocky substrates, often hiding in crevices during the day and emerging at dusk to feed and clean.
