Peat Bricks in the Vivarium

[ems1016]

I understand that peat bricks are a material that may be used to create embankments at the edge of water features. They are stable, do not erode, and provide a great base for growing wet-loving mosses. I'm thinking of using it along a portion of my river bank in a dart frog viv I'm building.

Could I have some opinions? (I searched "peat bricks" and got a "nothing found" response). Also, suggestions of where to buy it inexpensively?

Thanks!

I haven't really seen them used over here too often- they're more popular in Dutch vivarium builds, I think. Not too sure where you'd get something like that here... I know that some of the vivarium supply places over there carry them.
