Rare in still or slow-flowing waters, perhaps occasionally introduced from aquarium tanks or with other aquatic material, proliferating during the growing season, limited by availability of phosphorus. Apparently winter tolerant, capable of surviving under thin ice. Difficult to identify without megaspores, but fast-growing plants more than 2 cm long are more likely this species.
