Triple Open Cave Slate Hide 2.5"x2.5" I've personally used this sand3 chamber open backed hiding cave for fish and herps alike! Made with all aquarium safe materials that do not affect water parameters or degrade under heat UV. Due to the variation in the stone I work with, the cave you receive may have a different stone pattern. The structure measures approximately 6"x6"x6" and the opening measuring about 2. 5" x 2. 5", without a backing to allow your animals to move freely through. Check out my store for other sizes
