I recently purchased a small algae octopus. I've been hand feeding krill/silversides and threw a few snails and hermits in the tank as well, but I was curious about keeping the octopus entertained. Does anybody have any suggestions/recommendations of toys and such? I've seen using small loosely sealed jars to hold meals, but was looking for other ideas to keep it occupied throughout the day. Anything helpful would be greatly appreciated. Thanks.
