Honestly I have no idea what type of moss it is. I originally obtained it from a tropical greenhouse - it was growing in the very moist soil of a bog plant. I treated the moss for a period of time before introducing it to a viv. I originally started with a small clump about the size of a quarter and it has covered the majority of a ten gallon tank in a about a years time. The moss is very soft and holds up very well to frog traffic - it started on a coco bedding type mixture but quickly spread to all of the wood in the viv. I have received many inquires about the moss and I am in the process of starting cultures to trade, share, etc.
