Octopus Cyanea

Trevor Little

Hey guys I have been searching the forums to see if anyone had experience keeping these. Haven't seen any updated posts. Also curious if anyone thinks that I could keep this species in a deep 125g tank with cool cave structure. I'll upload a photo of the tank. Has a 30 gallon sump.

O. cyanea will outgrow a 125 (and even a tank twice that size) very quickly. I have often wished I could keep one but my reading indicates that not only are they a large octopus but they also tend to wander great distances, making a large public aquarium the only set up that would be appropriate.
