For freshwater aquaria, gravel is the most common substrate. To prevent damage to fish, gravel should not be sharp. Aquarium gravel can be as coarse as pea-sized or as fine as 1–2 mm. [1] It is available in a number of colors, and may be naturally colored or dyed, and may have a polymer seal to ensure it does not affect water chemistry. [1]
Aquatic plants are used to give the freshwater aquarium a natural appearance, oxygenate the water, absorb ammonia, and provide habitat for fish, especially fry (babies) and for invertebrates. Some aquarium fish and invertebrates also eat live plants. Hobbyists use aquatic plants for aquascaping, of several aesthetic styles.

Sphagnum girgensohnii, commonly known as Girgensohn's bogmoss, [4] Girgensohn's sphagnum [5] or common green peat moss, is a species of peat moss with a Holarctic and Indo-Malesian distribution. First described by Edmund Russow in 1865, it is a relatively robust moss species characterised by its green to straw-coloured appearance and ...
In the 2010s Sphagnum peat in Chile has begun to be harvested at large scales for export to countries like Japan, South Korea, Taiwan and the United States. Given Sphagnums property to absorb excess water and release it during dry months harvesting of Sphagnum, means that overexploitation may threaten the water supply in the fjords and channels of Chile.

Sphagnum is a genus of approximately 380 accepted species [2] [3] of mosses, commonly known as sphagnum moss, also bog moss and quacker moss (although that term is also sometimes used for peat). Accumulations of Sphagnum can store water, since both living and dead plants can hold large quantities of water inside their cells; plants may hold 16 ...
Muskeg consists of non-living organic material in various states of decomposition (as peat), ranging from fairly intact sphagnum moss, to sedge peat, to highly decomposed humus. Pieces of wood can make up five to fifteen percent of the peat soil. The water table tends to be near the surface.
Sphagnum rubellum, commonly known as the red peat moss, [1] is a species of peat moss in the family Sphagnaceae. It forms low, reddish cushions in wet areas like bogs and poor fens across North America and Eurasia, particularly in regions with oceanic climates. The species can vary in colour from green to pink or deep crimson, and grows up to ...
