Water Sprite 3x (Ceratopteris Cornuta) - Floating Fern - Live Aquarium Plant

Water Sprite (Ceratopteris cornuta) is an aquatic fern and resembles Ceratopteris thalictroides though the former has more delicate leaves. It is often sold as a floating plant where it develops a very ornamental root system that is suitable for the foam nest building labyrinth fish. However, it may just as well be grown as a rooted plant - and only the rooted individuals develop fertile leaves. The fertile leaves are folded inwards towards the abaxial - or lower - side where the sporangia develop.
