Cholla wood is the skeleton of a cholla cactus after it dies. The cholla wood is made up of many holes and is hollow through the center which provides a natural looking cover for small fish and shrimp to hide. A huge benefit of cholla wood is the fact that it grows a bio-film which is a main food source for shrimp. It also releases tannins into the water, similarly to Indian Almond leaves and other natural products. Cholla wood is a softwood and will eventually break down in the aquarium (6-24 months depending on thickness).
When added directly to an aquarium it will float and usually takes 24-48 hours to sink. To sink cholla wood immediately, it can be boiled for 2-5 minutes. Allow 30 minutes for the wood to cool before adding it to the aquarium.
