Cleaner Shrimp – Lysmata amboinensis

About this invertebrate

Cleaner Shrimp – Lysmata amboinensis is a saltwater cleaner shrimp that helps support reef aquariums by removing parasites and dead tissue from tankmates as part of its natural “cleaning station” behavior. In a home aquarium, it’s a peaceful invertebrate addition that can also be fed meaty foods to keep it active and healthy. Please note that, while it is commonly labeled as “scarlet cleaner,” this listing is for the confirmed species name Lysmata amboinensis for group-level care guidance.

Features:

• Removes parasites and dead tissue from fish using its cleaning behavior as fish present themselves.
• Peaceful temperament; compatible with a wide variety of reef fish (avoid known predators that may eat shrimp).
• Prefers secure spaces like caves, nooks, and crannies, and may be seen hanging upside down within shelters during daylight hours.
• Accepts a variety of foods in captivity, including pellets and frozen meaty foods, with a preference for meaty items.
• Best kept singularly or in pairs for calmer, more natural behavior.
• Sensitive to rapid parameter swings—keep salinity stable and acclimate slowly.
