Tired of your aquarium plants floating away before they can root? These volcanic rock plant anchors are the simple, natural solution. Each pack comes with 5 random-colored stones, each about 4.7 x 3.1 x 2 inches. They're made from porous volcanic rock, which is great for beneficial bacteria and is completely safe for your fish. Just tuck the roots of your water grass or stem plants into the center ring or under the stone, and it will hold them firmly in the substrate until they establish themselves. They also make excellent, natural-looking hardscape decor on their own, adding texture and a natural vibe to your aquascape. Because they're porous, they can even help with biological filtration. A super handy and affordable tool for any freshwater aquarium hobbyist trying to create a beautiful, planted tank.
