Peppermint Shrimp
Lysmata wurdemanni
Animalia›Arthropoda›Malacostraca›Hippolytidae
📍 Caribbean Sea & Western Atlantic
Translucent shrimp with red stripes. Famous for eating Aiptasia pest anemones. An essential pest controller for reef tanks.
Care Guide
Diet
Peppermint shrimp are opportunistic omnivores that primarily feed on Aiptasia anemones, making them excellent pest controllers in reef tanks. Supplement their diet with high-quality frozen foods such as mysis shrimp, brine shrimp, and small pieces of fish 2-3 times weekly. They will also consume algae, detritus, and leftover food particles, so regular feeding of the main tank inhabitants usually provides adequate nutrition.
Behavior
These peaceful, nocturnal shrimp are most active during evening hours and tend to hide among rockwork and coral during the day. They are social creatures that do best in small groups of 3 or more, where they exhibit natural schooling behavior and reduced stress. Peppermint shrimp are non-aggressive toward fish and other invertebrates, making them ideal community reef inhabitants.
Breeding
Breeding peppermint shrimp in captivity is extremely difficult and rarely successful in home aquariums. They have a complex larval development requiring specific plankton and water conditions that are nearly impossible to replicate outside professional facilities. Captive-bred specimens are virtually unavailable; nearly all specimens in the hobby are wild-caught.
Tank Mates
Small reef fish that occupy different zones and pose no threat to shrimp
Peaceful small goby that coexists well with shrimp in reef environments
Active but non-aggressive; occupies different habitat zones
Compatible with peppermint shrimp; both are peaceful reef cleaners
Can coexist but may compete for food and hiding spaces; monitor behavior
Peaceful algae grazer that shares similar habitat requirements
Common Diseases
Bacterial Infection
Discoloration, lesions on body, lethargy, loss of appetite, cloudy appearance on exoskeleton
Improve water quality through increased water changes and protein skimming; maintain stable parameters; remove affected individuals to quarantine if severe
Parasitic Infection
Excessive molting, rubbing against rocks, visible spots or growths on body, reduced feeding
Quarantine affected shrimp; perform freshwater dips (1-2 minutes) in dechlorinated water; maintain excellent water quality and increase aeration
Molting Problems
Inability to shed exoskeleton completely, stuck molt, death shortly after molting attempt
Ensure adequate calcium and iodine supplementation; maintain stable salinity (1.023-1.025 SG) and pH (8.1-8.4); provide low-flow areas during molting
Nutritional Deficiency
Faded coloration, weak swimming, poor molt quality, reduced feeding activity
Provide varied diet including frozen mysis shrimp, brine shrimp, and quality flake foods; supplement with vitamin-enriched foods 2-3 times weekly
