Phoenix Moss Facts

Besides Phoenix moss, Fissidens Fontanus is also commonly referred to as water pocket moss, palm moss, and US Fissdens. It got its most common name of Phoenix moss in Taiwan once it became part of the trading world. Although it’s habitat is mostly in North America, this moss has become extremely popular for aqua-scaping all over the world.

Just like other mosses, Phoenix moss does not have actual roots. Instead, it has tiny hair-like “hands” that help it attach itself to other surfaces or objects. It then uses its leaves and stems to be able to absorb all the nutrients it needs to survive.

Description

Fissidens Fontanus is generally dark green and will often vary in lighter or darker shades depending on how much it has aged. The younger leaves will appear light green, but change to olive green and black as they get older. Phoenix moss branches will grow up to 1 inch long and have thin, long, and sharp looking leaves. The leaves will all be attached to the stem in a very precise pattern.

 It can usually be seen growing in rivers or lakes on top of a variety of surfaces. Phoenix moss will attach itself to rocks or wood and form a round-shaped dome. Due to the specific way it grows, it will always tend to have a very round shape. Most attempts at trimming the plant to create a different look will be futile.

Habitat

Phoenix moss is relatively a newly discovered plant native to North America. It can be very easily found dispersed throughout most of Illinois and even Europe. As long as there is a natural high-quality wetland around, phoenix moss can easily be spotted. They can even be found growing in lakes as deep as 60 feet. Phoenix moss seems to thrive most fully submerged, although they might appear above the water on rare occasions. Regardless of where it is found, clean water supply and a cool shaded area are always essential.

Phoenix moss is quite sensitive to both temperature and light. It can actually survive during the winter but will turn fully brown during the summer due to an abundance of light and heat. The average temperatures in this native habitat will range from 59 to 77 degrees Fahrenheit. However, it should still be able to tolerate temperatures anywhere between 39°F and 78 °F without any issues.

PH Preference

Like many mosses, Phoenix moss tends to prefer acidic soft water to grow in. Ideal PH levels will be in a range of 6.0 to 8.0 but this Fissidens can survive more neutral levels.

Vivarium Type

This type of moss will do great in a variety of vivarium types. When deciding if rather or not to use this moss in a particular type of enclosure, be sure to go with setups that have aquatic features. Here are recommended vivarium Fissidens Fontanus will do well in:

Paludarium – Half aquatic/ half terrain-based enclosure.

Riparium – Mostly aquatic-based enclosure with some terrain features present.

Aquarium – Fully aquatic-based enclosure with little to no dry terrain.

Vivarium Placement

Fissidens Fontanus is an aquatic-based plant. Although it can survive above water, it will thrive better partially submerged or fully placed underwater. Since this moss can pretty much attach itself to any surface, it can be used to decorate stones, driftwood, and walls.

When used for decoration, it is usually better to place Phoenix moss closer to the front instead of secluded corners of the tank. This way its unique shape and vivid colors will help attract the observer’s attention to that particular area. Due to its smaller round shape, Phoenix moss can be used both in standard aquariums filled with fish as well as small nano tanks.

Substrate

Phoenix moss can grow on a number of surfaces due to its unique way of absorbing nutrients and shallow root structure. In the wild, this plant is typically found in rivers or lakes attached to rocks or pieces of wood. As long as there is clean flowing water, phoenix moss will usually be able to excel anywhere with little to no substrate.

Lighting

Phoenix moss does best in low to moderate light environments. Exposing this plant to direct sun will cause it to dry out. When setting up lighting within an aquarium, a high level of brightness would be ideal. The tank should not be in direct sunlight and preferably away from any type of artificial light that produces UV. Aim for cooler color lights that replicate a cloudy day.

Buy Phoenix Moss

When shopping for possible Phoenix moss for sale, expect a few key indicators you are buying the best quality plant. The moss should be snail free along with any other type of pest. The source of moss will usually be sold in small tissue cultures, ready for you to propagate. The batch should arrive fairly moist and in fairly good shape.

Phoenix Moss Care and Propagation

In the wild, Fissidens Fontanus uses spores to reproduce. These spores are created in a distinctive seed capsule called sporangia. When sporangia reach maturity and open up the spores get deposited onto a parent plant where they can grow. This process will continuously happen on its own and ensures that the moss remains bright green and full.

How to grow

Surprisingly, indoor aquariums can be the best locations to propagate Phoenix moss. These locations allow for better-controlled growth conditions and modifications to allow as much expansion as possible. It is not necessary to add carbon monoxide into the water since this moss does well without it.

The most effective method to cultivate Phoenix moss is by dividing the plant into smaller pieces. These pieces can then be tied down to a mesh/net with thread or fishing string. Doing so will ensure that the moss remains attached while it begins to stick on its own and regenerate.

Watering

Being that Phoenix moss is usually grown underwater, it will not really require any watering. However, just like Java moss, it will greatly benefit from a steady water flow. Stagnant water promotes algae growth, which will damage this plant and the whole tank. Periodic water changes as well as trimmings can help make sure that Fissidens Fontanus reached its full growth potential.
