Hygrophil is changeable, also known as Demo-cinema, belongs to the Acanthaceae family (Acanthaceae). The Latin name is Hygrophila difformis or Synnema triflorum.
Hygrophil mutable grows in Southeast Asia. The plant prefers marshland, also grows along the edges of ponds and in rice fields, it was brought to our country from Thailand.
The adult Hygrophil is mutable forming large dense bushes. The leaves are polymorphic; they change as the plant grows: in young hygrophil leaves, the leaf is round or slightly elongated, then, as the plant grows, leaves with a jagged edge are formed, and then the leaves are divided into deep segments. In adults, large hygrophil leaves resemble fern leaves, reach a length of 20 cm with a width of 15 cm.
Interestingly, if the plant is removed from the water, the leaves lose their segmentation and again become oval with smooth edges.
The color of the leaves is intensely green, but there is a variation of Cinema Demorphic, which has bright streaks on the leaves, which create an original beautiful pattern. Light green leaf hygrophil rosettes perfectly decorate any aquarium.
However, in a small aquarium it is necessary to monitor the growth of the plant and periodically shorten it, otherwise it will easily grow without supervision, covering the entire surface of the aquarium.
As a primer Hygrophil is changeable prefers coarse sand with a small amount of clay to fix the root, better diffused lighting, fluorescent or incandescent lamps. Although the plant develops normally and in low light, the brighter lighting gratefully responds with vigorous growth. Garden form Hygrophil more demanding to care in general and lighting in particular, prefers bright artificial lighting and access to sunlight.
The best water temperature is from 20 to 25 ° C. The plant is undemanding to the chemical composition of water, it is acceptable pH from 8 to 15, preferably a low content of hardness salts.
Hygrophil negatively reacts to the lack of microelements (especially iron), the symptoms – pallor of leaves, as well as sluggish growth.
Hygrophil changeable propagated by cuttings. From the adventitious buds grow new shoots, after the appearance of their roots on them, you can begin to multiply.
Young shoots must be carefully separated from the parent plant and landed in the ground.
The dense bushes of Hygrophiles look very attractive in the central or rear part of the aquarium, especially if it contrasts with other types of aquarium plants with a different shape and color of leaves.
