Sunday Invertebrates - The Blue Linckia Starfish

The Blue Linckia Sea Star (Linckia laevigata) is perhaps the most instantly recognizable star fish. The Blue Linckia sports a vivid light blue to violet blue color over it's entire body. Hailing from the Indo-Pacific region, this sea star can grow up to 16 inches, however most in the aquarium trade are between 2 to 5 inches. The minimum recommended aquarium size is 100 gallons or larger.

The Blue Linckia has an expected lifespan of 12 - 18 months in the aquarium, however most die of starvation. Bright lighting will ensure algae growth and help keep this echinoderm fed, as will occasional meaty foods fed directly to the mouth on the underside of the central hub.

Blue Linckia sea stars must be introduced SLOWLY to your aquarium, often over the course of several hours so that it can properly acclimate to your aquarium's specific chemistry. Once introduced to your tank, keep an eye on it to be sure it is not being picked on or eaten by hermit crabs. Because of the difficulty associated with keeping these gorgeous sea stars, the Blue Linckia is not recommended for beginners.
