What Is Willow Moss?
Fontinalis Antipyretica is a species of moss in the Fontinalaceae family. This moss is commonly referred to as willow moss due to its willow tree-like appearance. Though this moss is not a fairly new bryophyte to the world, it has recently become a more sought after plant to put in cooler water aquariums. Another reason for its recent rise in popularity may be due to the fact that Fontinalis shares a lot of visual similarities to the very well known plant, Java Moss.

Willow moss (Fontinalis Antipyretica) care guide

Willow Moss Facts
Fontinalis Antipyretica is commonly referred to as Willow Moss due to its striking resemblance to willow trees. This plant is also commonly known as Greater Water Moss, Common Water Moss, and Antifever Fontinalis Moss. An interesting fact about Fontinalis Antipyretica is its scientific name in Latin translates to “the water moss that stops a fire.” Not quite sure if it, in fact, lives up to its name but I can’t imagine many fires having much luck underwater… So willow moss has my vote!


Description
Willow moss has a very common look when comparing it to other aquatic mosses. As I stated earlier, this plant closely resembles Java moss. The distinguishable difference between the two is the size of the leaves and branches of each plant. Willow moss looks significantly larger, bearing a thicker branch and stem system as well as bigger leaves sprouting from it.

Fontinalis generally comes in various shades of green. The more sunlight it receives typically makes it darker. If the moss starts to brown or appear tannish in color, it either isn’t receiving enough light or above water for too long. The oval-shaped leaves that grow from willow moss can get up to a quarter-inch in length. The stringy stems that branch out from the base are firm, spinely, and can get up to 24 inches in length.

Habitat
Willow moss is thought to be native to the upper region of North America but can be found in Europe, Asia, and Africa. The environment this freshwater plant is accustom to is fast-flowing rivers and springs. This bryophyte is often found caught between stones and fallen debris in the wild.

One thing I find extremely interesting about this plant is its preference to tolerate lower temperatures than other mosses. Willow Moss is a cold water thriving plant, making it great for aquariums that house cold water inhabitants like Goldfish. Considerable temperatures will range between 59 and 82 degrees Fahrenheit.

pH Preference
Another well-liked feature with willow moss in the aquascaping hobby is it’s hardy tolerance to various types of water conditions. Most bryophytes typically like to stay around the acidic side of the PH scale… But this moss can tolerate PH levels as high as 8.5! That’s an awesome good-to-know fact if your current tank has hard water conditions and you really the idea of adding a tolerable moss to the enclosure. A thriving PH range to consider keeping this plant around would be anything higher than 5.5 but no higher than 7.5.


Vivarium Type
This type of moss will do great in a variety of vivarium types. When deciding if rather or not to use willow moss in a particular type of enclosure, Be sure to go with setups that have some level of aquatic areas. Here are recommended vivariums this plant will do well in:

Paludariums – Half aquatic/ half terrain-based enclosure.
Ripariums – Mostly aquatic-based enclosure with some terrain features present.
Aquarium – Fully aquatic-based enclosure with little to no dry terrain.
Vivarium Placement
When it comes to vivarium placement for this type of Fontinalaceae, it can go in a number of places as long as it remains fully submerged in water. Being a centerfold type of plant, it would do really well-accenting hardscapes in the foreground area of the enclosure. Place it around rocks or tie it to wood branches and allow it to fully establish itself before pruning. It should go in an area that receives some level of light and it will eventually creep its way horizontally making a nice lushes carpet.

Substrate
Substrates can play a role in helping willow moss anchor to the desired position. Any type of aquarium media will do fine for this moss since it will not need it to absorb nutrients. As I mentioned earlier, Fontinalis can latch on to any type of firm surface so the substrate is not an absolute necessity when caring for this plant. Rocks, wood, sand, gravel, and dirt are all-sufficient substrates that can be used to help lock willow moss into place.

Lighting
The chilly rivers this plant is native to have shaded and indirect sunspots this plant spends most of its time on. Fontinalis Antipyretica can handle moderately bright lighting scenarios but will do best in lower light elements. Avoid direct sunlight and bright light sources. Sunlight could alter the temperature of the vivarium resulting in a warmer, more undesirable water condition. This moss should be given moderate to low levels of artificial lights since it usually takes shelter in shallow riverbeds in the wild.

Lightweight and True to Size — Best for Casual Use
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
It is nice to see the Amazon Essentials brand expand from household essentials to apparel and shoes. I ordered the Amazon Essentials Men's Lightweight Knit Running Sneakers. The product is made in Vietnam and comes in a shoe box, which is nice. I've noticed that quite often, inexpensive shoes are delivered just in a plastic bag. The sneakers are ready to use and have no odors from glue, organic solvents, etc., which is common nowadays. I wear a size 9W or 9.5. These sneakers are 9.5 and feel like a typical 9.5 size, without surprises. The product is advertised as lightweight, and it is true. Each shoe weighs below 0.6 lb (265 grams). Inside is soft memory foam; the shoes sit on the foot well, snug enough and comfortable, and are easy to put on and take off. They seem like a good fit for spring and summer as casual footwear or for light gym use. The sole is simple and not designed for performance or high-impact activities. Overall, a solid, reasonably priced, comfortable everyday option, though not intended for serious running or training.

Budget buy while being as comfy and stylish as an expensive brand!
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
My 14 year old had been running his own business since he was 12. He does lawn care and snow removal. His go to shoes when it's too hot for his work boots has always been off brand hey d*de style ones which are terrible for that kind of work as they just don't have the ankle support. He's also had some Orthopedic arch supports custom made for him through the DR in the last year that he needs to use in whatever shoes he's wearing at the time. So I've been on the search for a simple pair of slip on shoes that he could wear while working long hours around our community. He's sent me this picture tonight before heading out. He said "I didn't feel like putting my arch supports in and these are so comfy that I don't even notice I don't have them!" They are sharp looking shoes that really stand out as of they were A high end pair! It's great that they can be an every day style or could be more of a sport shoe as they have the support and padding for both options. In our case they likely be green with in a day or two and it'll be interesting to see how well they wipe off between his work days. I can update this review once he's worn them a bit more. For now they have been perfect for versatility, size was true to size (I did order 1/2 size up, but only did that because he's growing so fast!) and they are definitely a great fit to a budget!!!!

Good purchase.
Size: Medium, Color: Black, Size: Medium, Color: Black
My daughter needed some black sweaters for work at Starbucks. Came across these and snatched one. Price was really good, it is soft, black color is vivid and did not fade after washing. Durable and well-made. Fits as expected...she wanted something loose on her to wear on cold nights over her shirt. Keeps her warm. It came pretty quickly. The material is soft and its comfortable to wear. Nice basic sweatshirt to have in your closet! Pleased with purchase 😊 hopefully this helps!! Oh we intentionally bought bigger for an oversized fit.
