Cephalopods; Not an ideal speciman to keep at all, but the bottom line imo is this, there are a lot of species that are not ideal to keep but a lot of people do. If you know the dangers and accept the consequences it ultimately boils down to your decision. I have not seen to many tanks that are escape proof for a cephalopod, very difficult to do, and if you have kids it is a silly creature to have in the house. Just my 2cents worth.
