Weeping Moss Facts

Being fairly new to the hobby, Vesicularia ferriei has yet to receive other nicknames besides weeping moss.

Besides the unique falling look, the creeping branches give off, the biggest noticeable advantage this moss has over other similar mosses…

It is its ability to tolerate higher levels of light.

Where most bryophytes wither away at anything stronger than low light, this plant will outlast and continue to thrive.

That fact makes this moss a good choice for smaller setups where lighting has a bigger influence on the overall scape in a vivarium.


Weeping moss is a pleurocarpous plant that generally grows up to an inch thick and has a vibrant green color.

As the fronds grow outward from the plant, they will begin to sag in appearance.

This moss has a traditional bryophyte rooting system that it uses to easily latch onto surfaces like wood or stone.


Weeping moss is thought to be native to China but can be found throughout most of Asia and Europe due to its newfound popularity in recent years.

This moss is commonly found in a freshwater type of environment on the shallow bed floors of riverbanks and lakes.

The average temperatures in this native habitat will range from the low 60s to the high 70s.

PH Preference

Weeping moss tends to prefer to be on the more acidic side of potential hydrogen.

In the wild, this plant is often found on very acidic wood logs or rocks with highly acidic surfaces.

Ideal pH levels will be in a range of 5.0 to 6.0 but weeping moss 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 weeping moss in a particular type of enclosure, Be sure to go with setups that have fully aquatic areas.

Here are recommended vivariums that this plant will do well in:

  • Paludariums – Half aquatic/ half terrain-based enclosure.
  • Ripariums – Mostly aquatic-based enclosures with some terrain features present.
  • Aquarium – Fully aquatic-based enclosures with little to no dry terrain.

Vivarium Placement

This moss is an aquatic-based plant. It will not do well partially immersed or fully placed above water for extended amounts of time.

However, it does thrive in locations water is flowing and completely engulfing the plant.

Place this plant in the foreground of the vivarium floor tied to rocks or wood pieces.

It will help provide coverage for small inhabitants like fry or shrimp.


Weeping 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 anchored to fallen branches or caught between rocks.

The aquarium substrate or surface used should be firm and easily allow moss to latch onto.

Wood, gravel, and sand are also sufficient textures that weeping moss can take sanctuary.


The freshwater environment Vesicularia ferriei is native to provides a realm of shade and some partial sun through shallow depths of open water.

Exposing this plant to too much light will dry or burn this moss out.

When setting up lighting within the vivarium for this moss, a high level of brightness would be ideal since the plant is indoors.

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 mimic a cloudy day.

Weeping Moss Care and Propagation

Vesicularia ferriei, in general, are pleurocarpous plants, meaning it grows outwards.

When propagated correctly, it will sprout small stems with spores on the tips that blow off and allow new colonies to begin growing.

This plant is a fairly forgiving plant when it comes to caretaking.

Keep water conditions ideal and moss should thrive on its own fairly well.

How to grow

The easiest way to propagate weeping moss will be to cut away sections of moss and replant them into other ideal areas of the tank for establishment.

Secure new clippings with cotton thread or super glue to help moss latch onto new areas.

Once weeping moss is established in the given location, it will begin stretching out its creeping branches again.

Use low ph water and moderate lighting to encourage growth and once acclimated, trim new culture masses to the desired look.


If weeping moss is kept fully submerged in low ph freshwater, it should do just fine without CO2 or added supplementation.

Avoid leaving moss in stagnant water and keep some level of current passing through the plant.

This will not only help the propagation phase but also provide fresh nutrients to circulate through the plant at all times.

If the plant is being placed above land, a high amount of humidity in the form of a fogger or mister will be highly recommended.
