Add natural texture and mixed color detail to indoor and outdoor displays with these smooth aquarium gravel pebbles. The lightly polished river rocks feature varied shades of brown, white, green, red, black, purple, and other natural tones for a decorative look. Use the small river rocks as aquarium gravel, fish tank decor, vase filler, succulent top dressing, potted plant cover, resin art filler, garden accents, or walkway decoration. They are safe for aquariums and suitable for water features. Each stone is about 0.35 in, and the 5 lb bag can cover about ten 6 in pots. The pebbles are fade resistant and smooth to handle, though natural variation and a small amount of broken stone may be present. These stones do not retain moisture for potted plants.
