Green ball - Moss ball (Cladophora aegagropila)

Cladophora aegagropila is not really a plant, but a ball of algae of 3-10 cm. A decorative exception to the rule of avoiding algae at all costs. It is usually found in shallow lakes where the wave movements create the round shape. In the aquarium, it must be turned at regular intervals to maintain the spherical shape. Cladophora aegagrophila can be divided into smaller pieces, which become spherical over time, or which form a flat carpet-like growth if attached to roots and rocks. Protected in certain places in Japan.
