Aquarium Accessories Porous Driftwood Shrimp Reptile Shelter Cholla Wood

Cholla wood is the skeleton of a cholla plant after it dies. The cholla wood is made up of a ton of holes and is hollow through the center which provides a natural cover for shrimp to hide. A big benefit of cholla wood is the fact that it grows biofilm which is a main food source for shrimp. It also releases tannins into the water, similarly to Indian Almond leaves and other natural products.Strictly speaking, cholla is not wood, but the skeleton of the cereus. Because of its natural and unique structure it is a brilliant hideout and an optimal retreat for all invertebrates. It is free of any chemicals as well as pesticides and additionally very rich in potassium, calcium and magnesium. Furthermore, a microbial biofilm is formed over time. Hence, shrimps and crayfish don't just hide inside the cholla wood, but intensely graze the surface time and again. The cholla wood is hollow inside and it sinks rapidly to the ground. Moreover, it can get planted with fern, moss or algae and gets more decorative as a result.
