Check the 10 lb pack size, the 2-4 mm grading and the brown finish against your layout plans before choosing an offer. If you want a natural-looking substrate for an aquarium, vivarium or terrarium, this is the key combination to confirm.
A Natural River Bed Look
The lighter highlights are part of what gives this substrate its textured appearance. If you are building a display around rocks, driftwood or planting, that kind of finish can help tie the layout together without needing a bright or artificial colour scheme.
