Fire Shrimp
Lysmata debelius
Animalia›Arthropoda›Malacostraca›Lysmatidae
📍 Indo-Pacific reef caves
Striking blood-red with white-spotted antennae — one of the most beautiful marine shrimp. Acts as a cleaner shrimp, setting up stations where fish visit to have parasites removed. Best kept in pairs.
Care Guide
Diet
Fire shrimp are omnivorous scavengers that feed on detritus, algae, and small organisms on the reef. Supplement their natural grazing with high-quality frozen foods like mysis shrimp, enriched brine shrimp, and finely crushed flake foods 2-3 times weekly. They will also consume leftover fish food and benefit from occasional vegetable matter like blanched spinach.
Behavior
Fire shrimp are peaceful and relatively shy, spending much of their time foraging along the substrate and rock crevices. They are famous for establishing cleaning stations where fish visit to have parasites removed, displaying remarkable symbiotic behavior. They are most active during dawn and dusk and do best when kept in pairs or small groups, though they can be territorial with unrelated shrimp species.
Breeding
Breeding fire shrimp in captivity is extremely difficult and rarely successful in home aquariums. They have a complex larval development that requires specific conditions and live food cultures. Most captive specimens are wild-caught, making successful breeding a significant achievement even for experienced aquarists.
Tank Mates
Peaceful reef fish that benefit from cleaning services and won't prey on shrimp
Another cleaner fish species that shares similar peaceful temperament and reef habitat
Can coexist but may compete for territory; provide adequate space and hiding spots
Similar water requirements and peaceful nature, though they occupy different ecological niches
Algae-eating snail that won't compete with shrimp and helps maintain tank cleanliness
Common Diseases
Bacterial Infection
Discoloration, lesions on body or antennae, lethargy, loss of appetite
Improve water quality through frequent partial water changes, maintain stable parameters, and consider antibiotic treatment in severe cases if quarantine is available
Parasitic Infection
Excessive scratching against rocks, white spots or films on body, rapid gill movement
Quarantine affected shrimp, perform water changes, and use copper-free parasite treatments designed for invertebrates
Molting Complications
Inability to shed exoskeleton, stuck molt, lethargy after molting
Ensure adequate calcium and iodine supplementation, maintain stable water parameters, and provide gentle water flow to assist molting process
Ammonia/Nitrite Poisoning
Lethargy, loss of color vibrancy, erratic swimming, death
Perform immediate large water changes, test and establish proper nitrogen cycle, reduce bioload through careful feeding
