Common name: cushion star

General information

The Cushion Starfish, Culcita schmideliana, is a unique and fascinating invertebrate commonly found in the reef aquarium hobby. This species is known for its pentagonal, pillow-like shape, which distinguishes it from the typical starfish appearance. The Cushion Starfish exhibits a variety of colors, ranging from brown to green, often with mottled patterns that help it blend into its surroundings.

Care

Culcita schmideliana requires a well-established aquarium with a sandy substrate and plenty of live rock to explore and forage on. They are generally peaceful and can coexist with a wide range of tank mates. However, they may prey on small invertebrates and sessile organisms, so they should be monitored in a reef tank setting. A varied diet including meaty foods and marine algae is essential for their health.

Reproduction

Reproduction in Cushion Starfish can occur through both sexual and asexual means. In the wild, they may release gametes into the water column for external fertilization. In captivity, they can also reproduce asexually by division, where a part of the starfish detaches and develops into a new individual.

Habitat

Culcita schmideliana is found in the Indo-Pacific region, from the Red Sea to the Great Barrier Reef. They inhabit a range of depths, often found on sandy bottoms or seagrass beds, where they can camouflage effectively. In the aquarium, they require stable water conditions and ample space to roam.
