Is a 20 LONG a large enough tank for a OCTOPUS

[dj synystr]

i was thinking about linking a 20 long to my tank system to house a bimac octopus. it will have an external custom overflow in the back cut out to drain into a exteranl overflow box, it will be a part of a sump, refugium setup running my 46 bow front. my question is about tempuature, tank size basically. i have done alot of reading but still nbot sure if this would be a sutable setup for a ocotpus. also if anyone could post pictures of there set ups for there octo's so i can get an idea of what others have done for there animals. thanks in advance.

It matters what species it is for. Some species can live in a 20G and others can't.
