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]
Fontinalis antipyretica, [2] greater water-moss, [3] or common water moss, is a species of submerged aquatic moss belonging to the subclass Bryidae. It is found in both still and flowing freshwater in Europe, Asia, Greenland and Africa. In North America it is found in most Canadian provinces with a seaboard and most US states except the most ...
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 ...
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 ...
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.
The use of peat is controversial since the harvesting of peat moss from peatlands (which includes unique habitats such as bogs and fens) can degrade these peatlands. Peatlands are home to a diverse range of plant and animal species. Peat also has a very slow accumulation rate, as little as 1mm per year, so they take a long time to regenerate.
Sphagnum cuspidatum is a dominant species in the bogs that it inhabits. [6] In wetlands, they consume methane through symbiosis with partly endophytic methanotrophic bacteria, leading to highly effective in situ methane recycling preventing large-scale methane emission into the atmosphere.
Sphagnum capillifolium, the red bogmoss, [1] northern peat moss, acute-leaved bog-moss, or small red peat moss, is a species of peat moss native to Canada, the northern United States, Greenland, and Europe. [2] Small red peat moss can be distinguished by its sweeping, outward-curving branches that resemble tresses.
