I used Black Slate to build a moss-covered cave in my aquarium. The stone holds moss well and looks natural. It’s easy to cut into smaller pieces for detailed designs.

The black and gray tones add depth to my terrarium. It’s stable and works well with my mosses. A bit variable in size, but that’s expected with natural stone.
