Usually ships in 1-2 business days from our fulfillment center

Fissidens Fontanus is one of our favorite aquarium mosses! This delicate gem features rich green hues and soft, feathery fronds. It is a very delicate live moss that may look matted when balled up, but once it attaches to aquarium driftwood or stones—it really shines, offering a unique texture that sets it apart from other aquatic mosses.

Fissidens moss is easy to care for and doesn't demand much in exchange for fluffy growth. Like all plants, its form and growth speed is noticeably different with CO2 injection and moderate lighting. However, it won't fuss if kept in low light or low-tech planted tanks. When established, it forms fuzzy, cushioned patches that offer excellent hiding spots for tiny freshwater livestock like shrimplets and fry. So, if you're looking for a low-maintenance aquarium plant for your aquascape that doesn't skimp on texture and, try Fissidens! You'll soon see for yourself why its a moss every aquascaper loves.

Aquarium plants can vary in growth form and may require time to transition to your aquarium environment, whether grown submerged or emersed. This transition period is a natural part of establishing healthy, long-term growth in planted aquariums.

From carpeting plants in the foreground to stem plants and larger species used in the midground or background, each plant offers a unique contribution to a balanced and natural aquascape. As plants adapt, it is normal to see minor changes such as leaf melt, color shifts, or new growth patterns as they settle into their new conditions.

We carefully inspect and prepare all live aquatic plants prior to shipping. While we do our best to minimize hitchhikers, we cannot guarantee plants to be completely pest or snail-free unless tissue culture options are selected.

Because live plants are perishable, some signs of transit stress may occur, including leaf loss or cosmetic damage. These are typically temporary and when when healthy roots are present, most plants will recover with proper care.

Aquarium mosses are highly adaptable plants valued for their texture and organic appearance. They are commonly used to soften hardscape gaps, or form detailed features such as moss-covered wood, rock accents, or tree-inspired layouts.

Moss can be attached to any porous surface using thread or aquarium-safe glue, where it will gradually grow and spread across the surface. It can also be left loose or floating for a more unstructured look. With careful trimming, moss is versatile and can be shaped as desired. (We recommend turning your filter off temporarily for trimming to control its spread)

Mosses grow best in stable conditions and clean water, and are well suited for both low-tech and high-tech planted aquariums. Their dense growth provides excellent cover for shrimp and small fish, making them both a functional and aesthetic addition to a wide range of aquascapes.

How Our Moss Is Grown and Sold
Our aquarium mosses are cultivated in different ways depending on the variety. Loose moss is typically grown floating in holding tanks. Moss grown on stainless steel mesh is pre-attached and naturally flatter, making it easier to use for moss walls, carpets, or attaching directly to hardscape.

Lost in the Moss: A Beginner's Guide to Aquarium Moss

With so many species of aquarium moss in the hobby, it can be overwhelming (in a good way) to pick which one works perfectly for your planted tank. You’d think it’s just moss, but each type provides a different look and overall effect when added to an aquascape! So, we’ll be covering six different types of aquatic mosses that are all popular and worthy of being added to your aquarium. We’ll start with Java Moss and work our way through Christmas Moss, Mini Christmas Moss, Spikey Moss, Peacock Moss, and Weeping Moss. For starters, the photo below depicts a single frond of each, in that order.

Aquarium moss is a staple for a reason! It can be attached to driftwood, rocks, or used to cover gaps in an existing hardscape layout. Common methods for attaching include using cotton thread (we like this one) or aquarium-safe glue. Moss is pretty indestructible, and basic care guidelines include keeping temperatures comfy (below 74°F) and keeping your water clean. That’s the bare minimum. If you want to do more, treat it the same as regular aquatic plants, and you’ll soon find its growth exploding!

"Plants are tewwww teaaa"

— Jackson C. (5/5)

Fissidens Fontanus

"Healthy golf ball of moss, and a very generous amount too, I was happy with it and in hindsight I should've just glued large chunks to the hardscape, but it still worked out. My only complaint, and it could take time, but not every clump looks like the photos on the product page, some of them that have clearly started growing do and have a nice green color, but we'll see over time how they develop."
