Azolla Caroliniana (Mosquito Fern)

Azolla is a small, fast-growing floating aquatic plant that forms dense surface coverage in planted tanks and pond setups. Also known as Mosquito or Water Fern, it’s a popular choice amongst aquarium hobbyists and pond enthusiasts.

Its tiny overlapping leaves resemble miniature water ferns, making it a great option for anyone in search of a unique, low-tech floater. Azolla is primarily green, but can produce a reddish-purple hue when kept under high lighting. It is a very fast-growing plant that will require periodic harvesting to prevent light blockage. Floating plants offer several benefits such as algae control, improved water quality and a sense of security for tropical fish.
