Hello all, I am in the process of setting up a 75 or 90 gal tank for either Octopus briareus (apparently comonly known as the Carribean Reef Octopus), or Sepia officinalis. I believe I have a source for the cuttle, but I am not aware of a source for a captive bred O. briareus. I will most likely go with the octo as the 75 or 90 is quite small for the cuttle. Because the cost of a chiller is prohibitive, I have decide on briareus instead of a bimac. Also, in an effort to keep cost low, I was wondering if anyone has the plans or knows of a link to such, for a good performing down-draft style skimmer appropriately sized for the preposed set-up. Any help would be greatly appreciated.
