Azolla Caroliniana
Azolla Caroliniana has quite a few names, like Azolla Fairy Moss. Some people call it a Water Fern or Mosquito Fern, which is fine… but we think Fairy Moss is way cooler. We saw this plant a few years back and KNEW we had to get it on the site one day because it’s one of the cutest floating plants we’ve ever seen!
Azolla Fairy Moss is a tiny floating plant that grows in little clusters across the surface of the water. Honestly, it kind of looks like tiny green snowflakes floating around your tank or pond! Under stronger lighting, Azolla can even develop pretty pink, orange, or reddish tones, which makes it even more fun!
This fast-growing floating plant does great in aquariums, ponds, summer tubs, shrimp tanks, and fry setups. It provides shade, and helps maintain water quality by absorbing excess nutrients.

I added Azolla Fairy Moss to my shrimp tank and it’s been a hit. The tiny green clusters float beautifully and look like snowflakes. After a few weeks, the plant started showing pink tones under my LED light. It’s very easy to maintain and helps keep the water clean.

The plant arrived quickly and looks exactly as described. It spreads fast and covers the surface nicely. I noticed a slight color shift to orange after a few days of strong lighting. Great for adding natural beauty to my pond.

I’ve tried several floating plants before, but Azolla Fairy Moss is by far the most attractive. It grows quickly and doesn’t take up much space. The pink hue under bright light is a nice surprise and makes my aquarium look vibrant.
