Among the aquarium plants, riccia floating is most widespread, due to its unpretentiousness. Other species of this genus are more demanding: they require special conditions of detention. Therefore, aquarists prefer to choose ricchia.
The unpretentious and unpretentious appearance of the plant is largely misleading. So, riccia can change beyond recognition the whole look of the aquarium. It can be kept not only as an underwater culture, but also on the surface of the water. In addition, it serves as a kind of refuge for fry of viviparous. Many fish prefer to use riccia as a place for spawning. Riccia is directly related to the circulation of substances in an artificial reservoir. Thus, it improves the whole microclimate of the aquarium.
Richcia floating is a moss, rich green in color, which, floating on the surface of the water, forms small islands. The plant consists of branching and interwoven flat plates: no rich, no roots, no leaves, no stems.
Under adverse living conditions, the plant changes its color to dark green, brown and even red-brown. Usually this color of the plant indicates that it fades. To survive the adverse climatic conditions, riccia is able to form spores. Darkening of the plates is always preceded by spores, however, as soon as the drought period has passed or the adverse conditions of riccia have been eliminated, it will again enter the vegetative form and assume its emerald color.
Widespread riccia was not only among aquarists, but also nature. She adapted to the peculiar migration, which makes its distribution widespread. The main distributors of riccia are waterfowl. Plates stick to their paws, which the birds transfer from one reservoir to another. If the reservoir conditions are suitable for richia, then it begins to grow rapidly and after a while fills with itself the entire water surface of the reservoir.
Aquarium richia prefers the same conditions as in the wild. At least they should be similar. The optimum temperature at which this plant feels good is in the range of 22-28C. However, richia can grow at temperatures from 15 to 30C.
Neutral soft water is the best suited for its growth. If the water hardness exceeds the mark of 8C, then richia practically ceases to grow. The water in the aquarium must be changed at least once every two weeks.
For lighting, fluorescent lamps are the best suited. The use of incandescent lamps is fraught with local overheating of richia. The distance between the lamps and the plant should be at least 10 cm, if necessary, water can be lowered to the desired level. This arrangement of lamps creates ideal conditions for the growth of riccia: light, heat and high humidity. If the water temperature is below 20 ° C or above 30 ° C, then soon the colony will begin to fade, change its color, decrease in size and disappear. However, this does not mean that riccia has perished. When the conditions of life in the aquarium are normalized, new plates of saturated green color will appear from the spores.
Underwater riccia is more capricious than that which floats on the surface of an artificial reservoir. She needs mineral fertilizers, top dressing and saturated CO2 water.
In the aquarium, floating riccia helps to solve a number of important tasks. It is not only a kind of tool for the design of the aquarium, but also serves as a top dressing for some mollusks, turtles and ampoules. It also creates ideal conditions for the breeding of ciliates and preservation of the offspring of some species of live-bearing fish.
