I keep cholla in my cray and shrimp tanks as the babies will hide in and under them.
Most pieces will be hollow which allows fish to hide easily. Fantastic features that make it ideal for a multitude of design styles in any aquarium.
Cholla unique qualities, and shapes make it the choice for Aquarium Wood. Cholla will float if allowed to dry out .
The piece you are buying is approx. 5" X 6" as laying in the picture.
You are buying the exact piece you see in the picture.
All the Cholla I sell has been power washed. Depending on how deep your tank is the Cholla may need to be soaked before it sinks all the way to the bottom.
