Lava Rock # 62 is black with a Zebra Rock and some very small accent rocks that make for good contrast
The Lava Rock measures 11" High x 14" Wide and weighs right at 10 lbs. All together the group weighs 19 lbs. and all the accent rocks are inert so they don't have any effect in your Aquarium, and they are safe for anything you keep in your tank.
It has all been cleaned, and you can use it right out of the box.
