FS - Large Natural Rock Cave - $30.00 Shipped
I have a nice size rock cave for sale. It's about 15 inches long and 4 inches tall. It will ship in a USPS Priority Flat Rate box. I will add assorted rocks in the extra space in the box for $30.00 shipped. That's works out to be about a buck a pound.
This type of rock has been tested and found not to alter the water chemistry. It's great for attaching moss and plants and it's perfect for shrimp tanks. They love to hide in the bubbles in the rock.
The rock was legally collected from private land being developed for commercial use here in Las Vegas and is legal to ship.
PM me if you have any questions.
