Well, this is my -opinion-. The Hammok selled at petsmart is light, so it floats where the suction cup is. It isnt above water level just a little under it, or on the tank floor. If that shell was on the Tank floorr i don't really know if your betta would see it as a hammok. I also read the petsmart hammok information, and it's supposed to be close to the surface of the tank. It also says that betta fish in the wild normally sleep near the surface. I would say you should glue it to the side near the top of the aquariumn. Maybe using glue isnt such a good idea sense you might want to take it off. Also just using a suction cup with the shell still make the shell sink?
If i am wrong please explain lol i also thought about doing this.
