Male flowers are pedunculate by the elongate, filiform base of the floral tube, not released from the plant at anthesis; sepals 3.5-5.0 mm long, petals 5 mm long.

Why are Elodea plants good for fish habitat?

Elodea is an excellent oxygen producer and frequently used by fish to protect fry. Dense populations of plants reduce the water temperature and oxygen concentrations when plants die in late summer. However, dense growth of this plant can create a nuisance, and its closed, compact structure is not ideal fish habitat.
