This moss is delivered as a novelty from ADA company. Callicostella prabaktiana moss is widespread in Southeast Asia where it occurs in moist to wet habitats, i.a. on stream edges. It is able to grow above and under water. In aquariums this medium to dark green moss has a creeping growth habit and attaches itself on wood or rock. Callicostella prabaktiana moss also called as Sumathra moss.

Callicostella prabaktiana moss grows slowly under aquarium conditions but is not very demanding. However we recommend at least medium lighting and a good CO₂ and nutrient supply. It is best tied to driftwood or stones.

This rare moss is interesting for the greening of the hardscape, also in small aquariums.

Callicostella prabaktiana mossa is a creeping moss with a wide distribution in the Asian tropics, where it grows on wet rocks and shaded riverbanks, among others. It resembles the species Callicostella prabaktiana moss very much, however, it can be discerned from the latter by missing papillae (tiny bumps) on the leaf cells as well as a less serrate leaf margin in the tip area. It is often considered a variety of this species, though (C. papillata var. prabaktiana). The creeping, irregularly ramified shoots have a flat leaf pattern and look a bit like those of the Vesicularia species. However, C. prabaktiana can be discerned from the latter e.g. by a thick double midrib reaching almost to the leaf tip, rather roundish, thick-walled leaf cells and its tongue-shaped shortly acute leaf form.
