I bought some for a tree frog set up and it's seems fine so far, But I want to know more.

First off, what the real name of the moss is?
How well it grows with other plants in the vivarium, and aquariums?
And will it grow, or is it basically dead and just holds moisture?

let me know your experiences with if (if any).
I wish these things came with better information.. =/

Thank you.
