The moss for cold tanks. Fontinalis antipyretica — Willow Moss — comes from cool, clear streams across the Northern Hemisphere and prefers water between 60 and 75°F. In an unheated or lightly heated tank, where tropical mosses sulk, this one thrives — growing long, flowing, willow-like fronds off rock and driftwood.

Grower’s Notes

• The temperature range is the reason to buy it. Most aquarium mosses want tropical warmth. Willow Moss wants 60–75°F — which makes it one of the very few mosses that works in a goldfish tank, an unheated room-temperature setup, or a coldwater biotope.
• Above 78–80°F it thins and browns. In a tropical community tank, use Java Moss or Christmas Moss instead.
• Tie or glue it thinly. Thick mats trap detritus and rot from underneath; a thin layer grows across the surface.
• Flowing fronds give shrimp and fry excellent cover and a large surface for biofilm.
• Arriving compressed and dark is normal. Rinse gently, place it in clean water, and colour returns within days.

Notes

• Live aquatic moss may appear slightly compressed or darker upon arrival due to shipping conditions. Simply rinse gently and place it in clean aquarium water; it will regain its vibrant colour and fullness within a few days.
• Some aquatic plants are restricted in certain U.S. states — check before ordering, and never release aquarium plants into natural waterways.

It is crucial to provide accurate and complete shipping information to ensure the successful delivery of your order and the applicability of the Live Arrival Guarantee.

Please keep in mind that Live Arrival Guarantee only guarantees that live stocks will be alive upon arrival. We cannot guarantee that you will continue to have success with them. Many factors, including the aquarium environment, water quality, nutrient, temperature, lighting, filter, and CO2 system, can contribute to the failure to grow live plants and live animals.

WHAT WE CAN'T GUARANTEE

Even though our plants are very clean, but we can't guarantee they will be 100% pest-free because we cannot be responsible for your aquarium. Please use it at your own risk. We recommended all customers rinse the plants with clean water and quarantine them before use.

However, plants in tissue culture will be 100% free from pests, algae and never have been contacting with any aquarium.

1. Due to the nature of the product. We don't guarantee our plants will be pests free. ( snails, algae, hitchhikers )
2. We don't guarantee our plants will be free of pesticides. We use homemade, organic pesticides in our greenhouse to control pests. We do not use pesticides that contain copper. Copper is toxic to invertebrates such as aquatic snails, crabs, shrimps, etc
3. We don't guarantee your aquarium success or are responsible for your aquarium inhabitant including but not limited to fish, shrimp, snail, turtle, etc. So please quarantine all plants when use!
4. Unless specific, we don't guarantee aquatic plants will be grow emerged or submerge.

Please review your state's regulations on restricted plants, as we are committed to not shipping plants that are restricted in your area. Do not release any plants into the wild or waterways, as this can harm local ecosystems by introducing invasive species.

Your cooperation in protecting the environment is appreciated. For continuously updated information, refer to the USDA State Noxious Weed list here.
