Give your betta a cozy retreat with this tunnel-style hideout! Designed to stick to the side of your aquarium using suction cups, it provides a fun and secure space for your fish to explore and rest.

I used 20mm suction cups from Amazon  - https://www.amazon.com.au/Suction-Without-Mushroom-Plastic-Suckers/dp/B07ZKRNXGH

Please see the attached photo of the suction cups I used for dimensions

I have included the drawing file in case you need to modify the suction cup hole size
