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.
