This moss is delivered as a novelty from ADA company. Callicostella prabaktiana 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 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.
