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.

Common Diseases

Bacterial Infection

Symptoms

Discoloration, lesions on body or antennae, lethargy, loss of appetite

Treatment

Improve water quality through frequent partial water changes, maintain stable parameters, and consider antibiotic treatment in severe cases if quarantine is available

Parasitic Infection

Symptoms

Excessive scratching against rocks, white spots or films on body, rapid gill movement

Treatment

Quarantine affected shrimp, perform water changes, and use copper-free parasite treatments designed for invertebrates

Molting Complications

Symptoms

Inability to shed exoskeleton, stuck molt, lethargy after molting

Treatment

Ensure adequate calcium and iodine supplementation, maintain stable water parameters, and provide gentle water flow to assist molting process

Ammonia/Nitrite Poisoning

Symptoms

Lethargy, loss of color vibrancy, erratic swimming, death

Treatment

Perform immediate large water changes, test and establish proper nitrogen cycle, reduce bioload through careful feeding
