The Avatar Swimming Rocks offers a totally different take on aquascaping within the aquarium! It is a pumice stone which is attached to the base of the aquarium via a virtually invisible line and suction cup. You can attach most aquarium mosses and other bare-roots aquarium plants such as Anubias and Java Fern, so that it appears your plants are just 'floating' in mid water. The pumice stone is pH neutral so it will not affect the parameters of the water.
