My name is Matt. I'm new to caring for Octopuses. I'm currently setting up a tank for a Octopus bimaculoides. I'm having a rough time trying to find an Octopus bimaculoides. I have a 90 gallon predrilled tank. I have a refugium filtration system rated for a 175 gallon aquarium. My protein skimmed is for a 220 gallon aquarium. Any help is appreciated. Thank you.

:welcome: to TONMO

unfortunately we are not aware of any place that is selling Bimacs. The few people that have them on here have caught them themselves on the California coast.


where are you located?

I live in Indiana. I could fly out there, but I think i'm going to start the hobby with a briareus. Any suggestions or info is appreciated. I have read Cephalopods by Nancy and Colin a few times, but outside of that book and TONMO forums i'm new to octopuses.

Review our articles (from the home page) for additional general reading but to get a good view of keeping brieareus, look at the top of the Journals and photos forum for the "List of our Octopuses" threads. The lists show the species and from 2008 through our current year have links to the individual journals. Two of the longer ones will be the ones for Kalypso (2008 Animal Mother) and Leggs (2009 CaptFish) as they were both obtained as very, very small animals and I will also throw in a reference to Kooah (2010 dwhatley) just because I am currently trying to raise two of her hatchlings.

Thank you to everyone for the warm welcome! I really enjoy this forum. I am extremely excited to start my journey with cephalopods. I will begin with an Octopus briareus. I am going to wait and get the right specimen though. I would be heartbroken if I received a specimen that is already entering it's senescent period. I plan on keeping a detailed forum once I receive my octopus briareus. My plan is to post a day by day "life journal" I am new to the hobby so I don't know how much anyone will benifit from my posts, but I will post them anyway.

90 Gallon Octopus briareus future home

Here is a pic of my 90 gallon Octopus aquarium minus an Octopus :smile: Please give me feedback on the rock formation and if it will be a suitable lair or den. Also I checked the oxygen level and it was 7.2 ppm. The temperature of my tank is 78 degrees. The salinity is at 1.024. Is that a sufficient level of oxygenation? I don't want to add an aerator. I overspeced the filtration and skimmer to avoid aeration.

Two questions. Can you lower the water level in the main tank? Sometimes this is not viable but it helps to have about 2" of air space at the top to help with escape issues. Along the same line, do you have a way to secure the top? Some people use heavy weights, some use industrial velcro (a pain IMO) and other use locks (my preference). Weights have been both successful and unsuccessful depending on the octo and where they are placed but the air space (in addition to one of the other suggestions) seems to help the most (especially in combination with slight overlap around the edges.

It is unlikely a briareus will use the piping. I have seen the hatchlings squeeze into small crevices but not the larger animals (the one you get will likely have a mantle size about the size of a lemon) so the LR is likely to be the primary denning area and the piping ignored. In my own tanks I have about twice what you provide so that there is denning area the full length of the aquarium. Whether or not this is necessary or even desireable is unknown, however, the additional filtration cannot be argued. I would NOT rearrange what you have as it look just right for denning but I would add an additional configuration where you have decorations and perhaps put the decorations closer to the front. A male may enjoy the sand area as SueNami tended to come to the front at times (but several would move the sand OUT of their dens).
