Leptodictyum riparium 1-2-Grow!

Leptodictyum riparium is a slender, upright moss that tolerates both high and low temperatures. Often called "fibrous moss," it's found in most parts of the world, but is believed to have originated in Europe. It has a deep green color and is slightly transparent. It's an undemanding and easy-to-care-for moss that can adhere to rocks and tree roots in the aquarium. Growth is vigorous and rapid, so regular trimming is necessary.
A plant that's generally good for beginners who want a unique effect in their aquarium. Moss is popular in nano aquariums and is often used as a substrate and for fry care.
