How to Care for Sexy Shrimp

written by Dave Burr

Sexy Shrimp acquired their name because of how they wave their abdomens back and forth. They are great in reef aquariums and do best if kept in groups of three or more individuals. They can often be found perching on the tentacles of anemones or LPS corals.

Predators: Triggers, larger Hawkfish, Groupers, Lionfish, and large predatory Wrasses may eat Sexy Shrimp. They are best kept with smaller reef safe fish.

Feeding: Target feed a varied diet of plankton and small pieces of meaty foods.

Growth: Maintaining proper pH, Ca, Alk, & Mg levels is important for shrimp. Providing additions of iodine will help the shrimp to molt and grow.

Acclimation: Take the time to do a drip acclimation with any shrimp as they do not tolerate rapid changes in water chemistry very well.

Care Level: Easy
Reef Compatible: Yes
Diet: Carnivore
Range: Indo-Pacific
Family: Hippolytidae
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates < .10ppm

Water Chemistry: It is important that proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing) , and magnesium levels (1260-1350 ppm) are maintained. Raising magnesium levels gradually up to 1400-1600 ppm can help to combat algae outbreaks, just keep CA and Alk in line as you raise the Mg. Nitrates should be below 10 ppm and phosphates should be below .10 ppm. We recommend doing a water change when Nitrate levels rise to 10 ppm. It is important to replace your phosphate media when phosphates rise to .10 ppm. Media Reactors make the most efficient use of your phosphate media by fluidizing it.

Dosing: Vivid Aquariums uses and recommends dosing pumps to automate the dosing of additives and keep your levels more constant. A dosing pump can alleviate the chore of manually dosing your aquarium with Ca, Alk, & Mg 2,3, or 4 times per week and will benefit your aquarium by keeping your levels constant through frequent small additions of Ca, Alk, & Mg. Our tanks all progressed when we switched from 3 manual dosings per week to 70 automatic dosings per week and we got a lot more work done.
