Tank designs for keeping an octo?


Aug 16, 2007
I would like to have an acrylic tank made specifically for an octo.

Does anyone have any good sure fire designs to keep an octo secure inside?

I am thinking of having the display with a sump and skimmer.

So I would have a drain, and then a return pump in the sump with a skimmer down there.
I just ordered an acrylic tank from glasscages.com specifically for an octo setup. When the owner called to confirm my order I asked him if the acrylic tops fit tight or was there a gap in the back like all glass. He told me it was a tight fitting lid and it would need to be trimmed for filters, etc. I'll post a pic when mine comes in. You may need to add some weight to the top however.
