Chaetomorpha
Chaetomorpha linum
Family: Cladophoraceae
📍 Worldwide in shallow tropical and temperate seas
The most popular refugium algae in the reef hobby — tumbling masses of stiff, wire-like bright green strands. Grows rapidly, exporting nitrates and phosphates as it's harvested. Provides a habitat for copepods and amphipods that migrate into the display tank as live food. Extremely hardy.
