Wanda Hudson –
The calvus cave fits perfectly in my 10-gallon tank. My betta fish uses it as a hiding spot and seems more relaxed. The slots are just right for movement and airflow. Easy to install and looks natural in the tank.
Wendy Nash –
Great addition to my aquarium. The height and slot size work well for my small corydoras. They use it frequently and it looks like a natural part of the tank.

I bought this for breeding purposes. The two slots provide good space for spawning, and the cave stays stable even during water changes. Very satisfied with the product.
