Fissidens Fontanus Moss Mat
Fissidens Fontanus, also known as Phoenix Moss, is a beautiful aquarium moss with a soft, feathery look. It grows in little fan-like patterns that give your tank a really natural, aged-in look.
This moss mat is perfect for shrimp tanks and aquascapes. Shrimp love grazing through the moss for biofilm, and baby shrimp or fry can use it as a safe place to hide. You can place the mat right on your substrate, around hardscape, or use it to help create a lush carpeted look without needing a high-tech setup!
Fissidens is a slower-growing moss, but that’s part of what makes it so nice. It stays neat, looks full, and doesn’t take over the tank as fast as some other mosses.

The moss mat looks very natural and adds a soft, aged feel to my shrimp tank. My baby shrimp have been using it to hide, and I’ve noticed more grazing activity. It’s easy to place and stays in place well.
Melanie McLean –
I used this mat in my nano tank with cherry shrimp. It’s slow-growing, which is perfect for a low-maintenance setup. The fan-like patterns are beautiful and give a realistic look.
Matt Martin –
Great product for creating a natural aquascape. The moss holds its shape and doesn’t spread too fast. My shrimp are active in the moss, and it looks more mature and lived-in.
Una Walsh –
Placed it around the hardscape and it looks great. It’s not a fast grower, which I appreciate. Works well with my existing tank setup and doesn’t compete with other plants.
