Common name: Nardoa Starfish

General information

The Nardoa Starfish, scientifically known as Nardoa novaecaledoniae, is a captivating marine invertebrate that adds both beauty and function to a reef aquarium. This species is characterized by its distinctive star shape, with multiple arms that can range in number, typically from seven to nine. The coloration of these sea stars can vary, often displaying a combination of tan, brown, and white hues, which helps them blend into their natural reef environment.

Care

Nardoa Starfish require a well-established aquarium with a stable environment and plenty of live rock to explore. They are generally considered reef-safe but may prey on small snails or sessile invertebrates. It's crucial to ensure that they have access to a varied diet, which can include detritus, small invertebrates, and organic films on live rock. They should not be kept with predatory fish or other creatures that may harm them.

Reproduction

Reproduction in Nardoa novaecaledoniae is typically sexual, with individuals releasing gametes into the water column where fertilization occurs. In the aquarium, breeding is rare, but hobbyists may occasionally observe larval sea stars developing from broadcast-spawned eggs.

Habitat

Nardoa novaecaledoniae is found in the tropical waters of the Western Pacific, particularly around New Caledonia. They inhabit coral reefs and are often seen on or near live rock formations at various depths. In the home aquarium, they require a spacious tank with ample hiding places and a sandy substrate to mimic their natural habitat.
