Monosolenium tenerum, also commonly known as Pelia moss, is a type of liverwort that is native to Asia. It is a beautiful and unique aquatic plant that can add a touch of greenery to any planted aquarium. Its appearance is similar to that of Riccia, but instead of floating on the surface of the water, it stays at the bottom of the aquarium and forms dense cushions.

The Monosolenium tenerum can grow up to 2-5 cm in height and is usually green in color. It is a brittle plant, which means that pieces of it may break off easily if it is not handled with care. To prevent this from happening, it is recommended to attach it to stones using fishing line or to place it in small clumps among other plants such as Eleocharis.

Once the Monosolenium tenerum has established itself in the aquarium, it is very low maintenance and easy to care for. It requires moderate lighting and a pH level between 6.5 and 7.5. It also prefers water that is soft to moderately hard, with a temperature between 20-28C.

To keep the Monosolenium tenerum healthy, it is important to provide it with enough nutrients. It can be fertilized using liquid fertilizers, root tabs, or CO2 injection. If the plant starts to turn brown or yellow, it may be a sign of nutrient deficiency or insufficient lighting.

Overall, Monosolenium tenerum is a beautiful and unique aquarium plant that can add a touch of natural beauty to any aquarium. With proper care, it can thrive and create a lush underwater environment for your fish and other aquatic animals.
