Mattonelle in Roccia Vulcanica per Muschio e Piante Fai-da-Te (Confezione da 10)

These tiles stack nicely along the bottom and the moss grabbed onto the porous surface within a couple weeks. I used 8 of the 10 to make a carpet across the front of my tank and it already looks filled in.

I was worried the porous rock would crumble in the water, but each tile holds its shape perfectly while giving my moss plenty of grip. My shrimp are already checking out the little crevices for hiding spots, and the carpet is starting to fill in nicely after just two weeks.

I was worried the porous texture wouldn't hold up underwater, but these tiles have stayed solid for three weeks now and my moss is already clinging to the little crevices. The dark rock blends nicely into the substrate while giving my fry plenty of hidden spots to dart into.
