Cholla Driftwood is the dried husk of the Cholla Cactus which is commonly used in shrimp tanks. It provides excellent shelter for shrimp while also stimulating growth of bio-film which provides a source of food to shrimp and baby fish. It can also be used to attach different mosses, Marimo Balls, Buce, Anubias, or other plants to create a natural looking sunken log in your aquarium.
Driftwood can leech tannins which can cause a slight yellow or brown tint to your water. This is natural and the effects will reduce over time. Boiling the wood prior to use can decrease the tannins leeching.
Size is around 4 - 6 inches in length and approximately 1.5-2 inches in diameter.
