The tunnel fits well in my 10-gallon tank. I used regular aquarium sand and it stays secure. My betta fish has started using it regularly, especially after I put a small piece of food inside.

It arrived quickly and looks nice. My guppies enjoy hiding in it. I had to add substrate as instructed, and it holds firm now. A simple but effective addition to the tank.
