I recently set up a tank specifically for a octopus. It is a 44 gal. pentagon RRcorner tank. I was planning on ordering one on line when my tank was all ready, but last weekend I saw two at the lfs for the first time ever. My question is that they tell me they are pacific octopus, although they do not know the scientific name for it, would this octopus get too large for a 44gal tank? Right now they have a mantle size of about 2-3 inches. Is there anything else special about pacific octopus? Any info would be appreciated. THanks.
