This plant is not only decorative. But also interesting: it can not just be planted like the others, but can only be "planted" with a rubber ring. Its lanceolate leaves sit on very short stems, which in turn release creeping roots. The anchor roots that escape from these creeping roots must be very carefully, so as not to injure, place on the substrate (a stone or, even better , a split snag) and render them "first aid" in rooting with a thin cord or elastic band. The leaves of this plant in natural conditions reach a maximum length of 40 cm, but in the aquarium grow only half. The Javanese fern breeds by forming new leaves along the propagating creeping roots. This plant prefers soft water and peat additives. As for the coverage of special claims, he does not. In this sense, it adheres to the usual natural conditions: in nature, M. Pteropus grows in a moist environment, completely or partially submerged in water, on shady banks and slopes. The water temperature should not be below 20 ° C.
