DIY Cleaning Sponge Octopus Toy

Teach your octopus to clean the tank! Get an aquarium cleaning sponge that is larger than your octopus or make your own by wrapping magnets with a cloth. Clean the tank with the magnet when your octopus is active and leave the sponge in the tank for your octopus to clean as desired. Consider praising your octopus with a treat when it moves the sponge.
