Riccia floating (Riccia fluitans) is an aquarium plant of the Riccia family (Ricciaceae).
Riccia floating, a type of liver moss is common almost everywhere. Occurs in standing and slowly flowing water bodies in areas with a moderately warm climate around the globe.
Riccia floating – very common aquarium plant, an open-cut saturated green moss that floating on the surface of the water and forms beautiful green islets. This plant has no leaves, no stems, no roots and consists of small branching and interlocking flat plates (thallus).
Riccia very often used as a natural breeding substrate aquarium fish, as well as shelter for fry. Some fish use riccia to build their nests.
Moreover, riccia can be used as a natural dimmer for plants that do not like bright lighting. In addition to using Ricci on the surface of the water, it can also be kept in the submerged state (for the first time such a method was proposed by the famous aqua-designer from Japan, Takashi Amano). For these purposes, a bundle of Ricii is laid on a stone or snag and secured with a small nylon net or thin fishing line.
Riccia grows through the net and sometimes it even has to be trimmed with scissors.
Content richies pretty easy. It feels great in both moderately warm and tropical aquariums. For good growth, soft water with a neutral or slightly alkaline cosiness is desirable.
If the water hardness in the aquarium exceeds 8 °, then the growth of Riccia slows down. The optimum temperature is 22-26 ° C.
If the temperature drops below 20 ° C, the growth also slows down, the plant is reduced in size and may even die. A weekly water change of up to 20% of the volume of the aquarium is recommended.
Riccia loves bright aquarium lighting, with its deficiency, it breaks up into separate pieces (not forming islands), and the lower layers can even rot. In summer, the plant grows very strongly and prevents light and oxygen from entering the aquarium.
Therefore, overgrowth Riccia need to thin out. special feeding is not needed. The plant gets enough nutrients with fresh water and with food for fish.
Breeding richies a very simple process that occurs by dividing the thallus. A few small branches, in a short period of time can grow to the entire surface of the aquarium.
