Common name: Fuzzy cowrie shell

General information

The Gold Cowrie, scientifically known as Erosaria miliaris, is a striking marine gastropod mollusk that captivates hobbyists with its vibrant golden-yellow shell. This species belongs to the family Cypraeidae, commonly referred to as cowries. The smooth, glossy shell of the Gold Cowrie is highly prized by collectors and is often used in jewelry and ornamentation. In the wild, these invertebrates are nocturnal, hiding during the day and emerging at night to feed.

Care

Gold Cowries require a well-established reef aquarium with plenty of live rock and hiding places. They are sensitive to water quality and require stable conditions with low nitrate levels. Their diet consists mainly of algae and detritus, so maintaining a clean tank with a small amount of algae growth is beneficial. They are generally peaceful and can coexist with a variety of tank mates that do not pose a threat to them.

Reproduction

Reproduction in Gold Cowries involves the female laying eggs in a secure location, often under rocks or in crevices. The eggs hatch into free-swimming larvae that eventually settle and metamorphose into the adult form. In the aquarium, breeding Gold Cowries can be challenging due to the need for precise water conditions and the difficulty in raising the larvae.

Habitat

Erosaria miliaris is found in the Indo-Pacific region, from the eastern coast of Africa to the central Pacific islands. They typically inhabit coral reefs and lagoons, often at depths where light penetration allows for the growth of algae, their primary food source.
