Brazilian Peristomist (Myriophyllum brasiliense) or, as it is called, Uruti Brazilian – aquarium plant of the Slanagodnik family (Haloragaceae).
In natural habitat perististeum brazilian widely distributed throughout North and South America.
On long stems perististica brazilian there are small feathery leaves, painted in bluish-green on the surface and bright green color in the water column. With the end of daylight hours, underwater leaves are closing, opening again at dawn.
Many types of aquarium fish use the leaves of this plant as a place for spawning.
Uruti Brazilian – Aquarists have a very popular plant. For content this plant will fit aquarium any size.
AT aquarium is a great place for spawning, a refuge for fry and decorative decoration. Relatively unpretentious in content a plant that grows well in aquarium moderately warm or tropical type.
The optimum temperature for plant development is 18-26 ° C. It tolerates short-term temperature drops to 12 ° C.
The best thing peristristis grows in soft neutral or weakly acidic water (pH 5.5-7, hardness up to 6 °). Aquarium plant forms dense thickets in the water column, which must be clean, without particles of turbidity, as settled turbidity on the leaves disrupts their food and leads to a gradual death.
Therefore, a weekly replacement of 1 / 4-1 / 5 of the total water volume in aquarium. To conditions lighting increased demands.
With weak, dim lighting peristristis loses its specific color and is drawn out. With natural light, the plant must be protected from direct sunlight, as it quickly acquires algae. As sources of artificial lighting suitable fluorescent lamps, with a capacity of 0.5 W / l, or incandescent lamps.
The duration of daylight can be determined by the behavior of the plant – as soon as perististeum brazilian begins to fold the leaves, it’s time to finish the day. In this case, the light turns off in about half an hour.
Have this aquarium plants the root system is tender and poorly developed. Therefore, it is recommended to use sand laid 3–3 cm thick as a primer. You can also contain peristristis floating in the water column.
The plant does not need additional fertilizer with mineral fertilizers, being fully satisfied with the substances supplied with fresh water or fish feed.
Breeding perististica brazilian possible by cutting the stem. The plant must periodically thin out and shorten its stem, removing the top.
Such a stalk is transferred to the ground, deepening the verticil of leaves, at the base of which the roots are formed fairly quickly. In winter, the natural day length is reduced and for the comfort of the plant in aquarium reduce the temperature of the water.
However, it is not necessary to do so. With sufficiently bright artificial lighting peristristis grows well throughout the year.
