I have an extra 60g tank, that i was thinking about putting an Octo in, I've done some reading, but can only really find info on Bimac's. I'm in AZ and my water temps stay around 78, which would mean I would prolly have to get a chiller for this guy. Any other octo's that would fit in this tank, that I could get my hands on, that don't require a chiller?? If not I have a friend that would let me borrow one of his extra's, I think it is 1/3HP, a little overkill but it would be free. Give me some feedback please. I saw lots of different Octo's for sale on these links http://is.dal.ca/~ceph/TCP/sources.html and was just curious if I could put any of them in my 60 gal. Thanks again.
