Measure your tank carefully BEFORE buying. 

How to use: Place the tunnel against the glass and add 2.5 inches of substrate to hold it in place. The extra large tunnel will need 3 inches. This item will not work without substrate.

The corner tunnel will enrich your fishes environment. The fish can hide and explore but you can still see them! To encourage your fish into the tunnel you can put some food into it. 

**Due to the nature of this product we do not offer returns. Please check tunnel sizing before buying to take sure you fish will fit and it will fit your tank. Whilst our fish love the tunnels we cannot guarantee all fish will use it.

This Item will not work without substrate.
