Ok, my remaining two octpouses (unfortunately #1, affectionately known as Blinky, died while I was away working of unknown causes. We think he might have been sick beforehand.) are doing just fine in their larger, now cycled tanks. I do worry, however, that they may be bored. I have lots of various shaped pvc pieces in the tank, and I know #2 (Clyde) likes to play in the air bubbles every so often, but the excitment of their surroudnings seems to have worn off. I know Clyde leaps after my hand every time I go to take a water sample or scrub the tank, but I think he gets upset with me when I won't let him eat it, lol. He has quite a grip! Anyway, I was wondering if anyone had any suggestions as to what I might put in the tank to make things more interesting for them? I clean the tank with a sort of "sponge on a stick", which Clyde seemed interested in the other day, and in which Inky (#3) showed mild interest. I am going to try a sponge tied to a pipe as a toy and see how they like it. Any suggestions would be welcome. I want to keep my octos happy!
