Ive had my O. cyanea (Neptune) for about 3 months now. I keep him in a 125 gallon aquarium. I have trained him to open jars and tupperware containers but I cant help but feel that he is bored. I was wondering what people have put in their tanks to let their octopuses play with. I have been thinking about tying something positively buoyant to the rocks to see if it would interest him. I have also thought of getting one of those bubbling chests, Ive heard bubbling is bad for octos, but the air flow would be minimal. Does anyone have any other ideas?

There are a number of things to try. First of all, are you giving him live food? Hunting is one the best forms of enrichment.

Then there are the toys, and not all octopuses like toys. YOu could try making a little structure from a couple of drinking straws, that's been a favorite before. Some will play with the large Lego blocks, other like those rubbery creatures used on artifiical lures for fishing (all hooks and extraneous material removed). Some like a sturdy little bottle, or a pile of shells. But honestly, you playing with him may be the greatest source of entertainment.

You might search on toys because we've discussed this before.

Yes, he is fed mostly live food (as catching permits) and thanks, I will try some of those out.
