Description
The Painted Starfish Hunter Arguably one of the most beautiful and ornate invertebrates in the ocean, the Harlequin Shrimp is a true living jewel. With a creamy white body adorned in a breathtaking mosaic of purple, pink, or blue spots, and unique, flattened claws that resemble flower petals, this shrimp is a work of art. They move with a deliberate, swaying grace and are almost always found in a devoted male-female pair, adding another layer of fascinating social behavior. These shrimp are not just beautiful; they are captivating to watch. They are active and intelligent hunters, exploring their environment with purpose. Owning a pair of Harlequin Shrimp is like having a constantly evolving art exhibit in your aquarium. However, their stunning beauty is matched by their highly specialized nature, making them a rewarding challenge reserved for the most dedicated and prepared aquarists. An Essential Note on Diet: For the Dedicated Aquarist Before considering a purchase, it is critical to understand that the Harlequin Shrimp is an obligate predator of starfish. They eat ONLY starfish and will starve to death without them. They will not eat mysis shrimp, pellets, flakes, algae, or any other prepared foods. There are no exceptions. A consistent food source, such as a supply of live Chocolate Chip starfish or a culture of pest Asterina starfish, must be secured before you acquire these shrimp. This is an expert-level animal solely due to this strict dietary requirement. Why the Harlequin Shrimp is a Breathtaking Addition: Unparalleled Beauty: Their vibrant colors and ornate patterns are unmatched by almost any other shrimp in the hobby. Fascinating Predatory Behavior: Watching a pair work together to hunt and consume a starfish is a stunning, National Geographic-worthy display of natural behavior. Bonded Pairs: They form a true male-female bond and are one of the few invertebrates that can be kept as a dedicated pair. Natural Asterina Control: They are the ultimate solution for aquariums overrun with pest Asterina starfish. Care & Specifications Success with Harlequin Shrimp is 100% dependent on meeting their dietary needs. Their water parameter and tank requirements are straightforward, but their food source is not. Feeding: The Only Thing That Matters Diet: Starfish (Echinoderms). Primary Food Source: Most aquarists feed them live Chocolate Chip starfish (Protoreaster nodosus). A single starfish can sustain a pair for one to three weeks, depending on its size. The shrimp will consume the starfish’s tube feet first, keeping it alive for as long as possible. Asterina Starfish: For smaller tanks or for those who don’t wish to feed larger stars, a separate, dedicated tank for culturing pest Asterina starfish is a viable option. Frequency: A constant supply of food must be available. Do not wait for them to finish one starfish completely before having the next one ready. Tank Requirements: Minimum Tank Size: 10 Gallons for a pair. A dedicated species tank is highly recommended. Aquascape: Requires mature live rock with plenty of caves and crevices for hiding, especially during molting. Water Parameters: Temperature: 75−82°F (24−28°C) Specific Gravity: 1.023−1.025 pH: 8.1−8.4 Ammonia, Nitrite, Nitrate: As close to 0 ppm as possible. Iodine: Like all crustaceans, they benefit from iodine supplementation to aid in healthy molting. Compatibility: Temperament: Peaceful towards fish and corals. Reef Safety: They are 100% safe with all corals. However, they will hunt and kill ALL desirable echinoderms. Do not house them with ornamental starfish of any kind, including Serpent, Brittle, Linckia, or Sand-Sifting sea stars. They will also consume sea urchins if other food is scarce. Tank Mates: Keep with peaceful fish. Avoid aggressive predators like Triggerfish, Pufferfish, and large Wrasses that would prey on the shrimp. Acclimation: IMPORTANT: Harlequin Shrimp are delicate. To ensure a smooth transition and prevent unnecessary stress, slow drip acclimation over a period of at least 60-90 minutes is mandatory.
