Common name: Sand Dollars
Scientific name: Astriclypeidae
Astriclypeidae is a family of echinoids commonly known as sand dollars. These invertebrates are characterized by their flat, round bodies and intricate petal-like patterns on their upper surface. They are found in sandy or muddy substrates in shallow waters. In the aquarium, sand dollars require a tank with a deep sand bed to burrow and sift through for microorganisms and detritus. They are sensitive to water quality and require stable conditions with low nitrate levels. Sand dollars are fascinating additions to a peaceful reef or invertebrate tank, but they are not recommended for beginners due to their specialized care requirements.
