Goniodiscaster scaber

Datasheet

General Description

The Red Biscuit Sea Star, scientifically known as Goniodiscaster scaber, showcases a captivating mosaic pattern of red and white, adding a vibrant touch to marine aquariums. Belonging to the Asteroidea class, these sea stars exhibit the unique ability to engage in both asexual and sexual reproduction, with embryos hatching into larvae and developing into young sea stars with stubby arms. They are commonly found in seagrass habitats with low canopies and are primarily active during the night.

Aquarium Suitability

The Red Biscuit Sea Star is an omnivorous creature, known to scavenge on coral rubble and prey on tubeworms in its natural habitat. In aquarium settings, they thrive on a diet of zooplankton, finely chopped meaty foods, and liquid invertebrate food. With a max size of approximately 10.2cm, this species is generally considered easy to care for in captivity.

Demands, Care, and Hardiness

This species of sea star garners an easy care level, making it suitable for aquarists of various experience levels. It is important to maintain stable water conditions with a pH ranging from 8.1 to 8.4, a specific gravity level between 1.023 to 1.025, and a carbonate hardness of 8-12 dKH. Despite its hardy nature, care must be taken to ensure a suitable environment and appropriate diet to support its overall well-being.

Reef Suitability

The Red Biscuit Sea Star is classified as not reef-compatible due to its aggressive temperament. While it can be a visually striking addition to a marine aquarium, caution should be exercised when housing them with other reef inhabitants to prevent any potential harm or disruption within the ecosystem.

Aquarium Setup

When setting up an aquarium for the Red Biscuit Sea Star, it is crucial to provide ample hiding spots and spaces for foraging to mimic its natural habitat. A well-established tank with live rock structures, low canopy areas, and sandy substrates is ideal for promoting the sea star's natural behaviors and ensuring its overall health and comfort.

Behaviour

Known for their scavenging nature, Red Biscuit Sea Stars exhibit active feeding behaviors, especially on coral rubble and tubeworms. Their nighttime activity pattern makes them intriguing to observe in aquarium settings, adding a dynamic element to the tank's ecosystem.

Feeding and Diet

As a carnivorous species, the Red Biscuit Sea Star thrives on a diet consisting of zooplankton, finely chopped meaty foods, and liquid invertebrate food. Regular feeding schedules and varied diet offerings contribute to the sea star's nutritional needs and overall health maintenance.
