Common name: Blue Linckia Starfish

General information

The Blue Linckia Starfish, scientifically known as Linckia laevigata, is a striking marine invertebrate popular among reef aquarium enthusiasts. Its vibrant blue coloration and unique shape make it a visually appealing addition to any tank. This species is known for its remarkable regenerative abilities, capable of growing an entirely new starfish from a single arm.

Care

Caring for a Blue Linckia Starfish requires a well-established reef aquarium with plenty of live rock for grazing. They are sensitive to rapid changes in water parameters, so maintaining stable conditions is crucial. A varied diet of detritus, microalgae, and small invertebrates will help keep them healthy. It's important to note that they can be sensitive to copper-based medications and high levels of nitrates.

Reproduction

Reproduction in Linckia laevigata can occur both sexually and asexually. In the wild, they release gametes into the water column for external fertilization. Asexually, they can regenerate from a single limb, a process that can take a considerable amount of time. In the aquarium, asexual reproduction is more common, though it is not a frequent occurrence.

Symbiosis

While not known for specific symbiotic relationships like clownfish and anemones, the Blue Linckia Starfish can contribute to the overall health of the reef by consuming detritus and helping to control algae growth.

Habitat

The Blue Linckia Starfish is found in the Indo-Pacific region, typically in shallow, coral-rich environments. They are often seen on reef flats and slopes, where they can blend in with the blue hues of the water and sky.
