WIO Darwin Black Lava nano rocks
These naturally volcanic rocks will add texture and contrast to any display. With their many clefts and pockmarks they provide interest that would combine well with epiphytic plants such as Anubias, Microsorum and Bolbitis. They can also be used in a biotope, such as for a stream on an Indonesian volcanic island!
