Universal Rocks Decorock-044-20 Decorative Artificial Texas Holey Rock, White Universal Rocks does *NOT* use paints and chemicals in the coloring process of our product, the natural sands and aggregate in and on our rocks that are used are all inert, to achieve the most natural feel and look possible. Sometimes small amounts of color maybe dispersed into the water but will significantly reduce overtime as does real rocks and substrates in an Aquarium. Be aware when disturbing an aquariums existing decor or substrate, it can lead to the release of idol aerobic and anaerobic (very toxic) bacteria into the water causing distress and even death to most fish and living organisms within the aquarium. If there has been a lot of disturbance we suggest a partial water change or use of a water conditioner such as "Prime" sold by Seachem.Item measures 34" L x 5" W x 19" H This item is not intended to be viewed in a 360 degree manor as it does not have the rock texture on the back.
