Calcium carbonate derived from oolitic aragonite is biogenic (created by living organisms) and naturally re-occurring. Protect the reef by using this superior and sustainable substrate.
Add the Marine Accents to any aquarium for spectacular effect. Each piece of fossilized aragonite and shell is one of a kind natural sculpture. These unique accents will complement any reef structure and are recommended to be placed in the forefront of an aquarium and scattered around at random intervals.
I would definitely recommend adding these little guys to your tank. They are very playful and entertaining. My three were very healthy and quickly adjusted to my tank.
