The Sexy Shrimp is a tiny reef favourite known for its signature tail-wagging dance and bold personality for its size. These shrimp love to perch on corals and anemones, often gathering in small groups and moving in sync. They are reef safe, peaceful, and perfect for nano reefs, but they do best with gentle tank mates since they are small and can be targeted by larger fish.
Why we love it
-
Iconic tail-wagging “dance” and tons of personality
-
Perfect nano reef invert with great color and movement
-
Often groups together for a fun, social look
-
Reef safe and coral friendly in most setups
Care and Compatibility
Care Level: Easy
Temperament: Peaceful
Reef Safe: Yes
Diet: Omnivore (scavenger)
Adult Size: ~1"
Minimum Tank Size: 5 gallons recommended (10g+ ideal for groups)
Feeding
Sexy Shrimp are easy to feed, but they benefit from occasional targeted feeding.
-
Leftover fish food and frozen food scraps
-
Small sinking pellets for inverts
-
Tiny meaty foods like mysis, brine shrimp, and finely chopped seafood
Feeding after lights dim can help in busy tanks.
Tank and Setup Notes
-
Provide rockwork and corals or anemone hosts for perching
-
Stable salinity is very important for shrimp
-
Gentle flow areas help them perch comfortably
-
Be careful with powerheads and overflows, use guards when possible
Compatibility Tips
-
Best with peaceful nano fish like small gobies and firefish
-
Avoid hawkfish, many wrasses, dottybacks, and other predators that may eat small shrimp
-
Usually safe with corals, but can irritate some polyps if kept in large groups
-
Works great in groups of 3 or more in larger nano reefs
Acclimation and Health
Drip acclimation is recommended. Once settled, they are hardy, but they are sensitive to sudden salinity changes. Provide hiding spots and make sure they are not being outcompeted at feeding time.

Collapsible content
LIGHT
LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.
MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height.
HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.
FLOW
LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.
MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.
HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.
SKILL
ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.
While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
