Common name: Cockles

The Cardiidae family, commonly known as cockles, encompasses a variety of bivalve mollusks found in marine environments. These invertebrates are characterized by their rounded, heart-shaped shells with radial ribs. Cockles are filter feeders, sifting plankton and organic matter from the water. In the aquarium, they can help maintain water quality by reducing excess nutrients. They require a sandy substrate to burrow and a stable environment with moderate flow. Cockles are generally peaceful and can coexist with a wide range of tank mates.
