Description ANS CHOLLA TUNNEL TUBES SINGLE S (10CM) Cholla Driftwood comes from the dried husk of the Cholla Cactus and is popular in shrimp tanks. It offers great hiding spots for shrimp and encourages bio-film growth, which serves as a natural food source for shrimp and baby fish. You can also attach mosses, Marimo Balls, Buce, Anubias, or other plants to create a natural sunken log effect in your aquarium. The wood may release tannins, causing a slight yellow or brown tint in the water, which will fade over time. Boiling before use can help reduce this.
