A very special rarity, belonging to the diverse family of the Filmy Ferns. This tiny, moss-like fern was found in southwestern India on rocks along a stream. It is not yet identified with certainty and likely belongs to the species Crepidomanes malabaricum. In its natural habitat it is flooded during the rainy period only, however it can be grown permanently submerged in aquariums. This fern has tender, dark green, transparent leaves on a thin, creeping rhizome.
It is recommendable to fix Crepidomanes cf. malabaricum on stone or wood, you may also leave the plant on the pad and place it in the aquarium foreground. This fern grows very slowly, forming a carpet by and by. It is rootless but develops dark, hair-like rhizoids on the rhizome which help it adhere to the substrate. This Crepidomanes doesn't need much light, but a good CO2 and nutrient supply, soft to medium hard water and a good water current are beneficial.
Crepidomanes cf. malabaricum is a great enrichment for the aquascaping and looks particularly good in small-scale, delicate layouts, for example on vertical structures of the hardscape. Because of its extremely slow growth, one should pay attention to keep it from overrunning by other plants such as faster growing mosses.
