Common name: Blue Linckia Starfish

General information

The Blue Linckia Starfish, scientifically known as Linckia guildingi, is a striking marine invertebrate popular among reef aquarium enthusiasts for its vibrant blue coloration and unique appearance. This species is often found in the tropical waters of the Indo-Pacific region. It is known for its ability to regenerate lost limbs, which is a fascinating aspect of its biology. The Blue Linckia is a peaceful creature that can add both beauty and interest to a well-established reef tank.

Care

Caring for a Blue Linckia Starfish requires a stable, mature aquarium with plenty of live rock for grazing. They are sensitive to changes in water quality, so maintaining pristine conditions is crucial. A slow acclimation process is recommended when introducing them to a new tank to prevent shock. They feed on biofilm and microorganisms found on live rock and sometimes on the aquarium glass. Supplemental feeding is not typically necessary, but they may benefit from occasional offerings of finely chopped meaty foods.

Reproduction

Reproduction in Linckia guildingi is both sexual and asexual. In the wild, they can reproduce by releasing gametes into the water column during spawning events. Asexually, they can regenerate a new individual from a single arm, although this is less common in the aquarium setting. Hobbyists rarely witness reproduction as it often occurs unnoticed.

Habitat

Blue Linckia Starfish are found in a range of reef habitats, from shallow lagoons to deeper reef slopes. They prefer well-lit environments where they can find ample microfauna to graze on. In the aquarium, they require ample space to roam and a stable environment that mimics their natural reef habitat.
