Harlequin Shrimp, Hymenocera elegans, is a small decorative shrimp with a maximum body size of 1 1/2 inches. They are better kept as a bonded/mated pair with the male being slightly smaller than the female. The claws of the harlequin shrimp are large and purely decorative, they are not used for hunting. These shrimp eat only starfish and some sea urchins. In aquaria, it is easier to supply a steady diet of live asterina starfish. Some aquarists see these starfish as pests thus making the harlequin shrimp a highly valuable invertebrate.
Slow temperature acclimation: 15-30 min
Dripping is the preferred method of acclimation for all inverts. Most invertebrates will do well with a 1 hour drip. More sensitive invertebrates like starfish and urchins should be dripped for longer.
The AccuDrip by Innovatiove Marine is an excellent, affordable, acclimation tool to make dripping marine inhabitants easy and pain free.
Notes for Success:
- Make sure there is no significant change in water temperature while acclimating.
- They are not tolerant of high nitrates
- They are not tolerant of copper medications
