    [Octopus]: New Bimac

    I was lucky enough to order one of @Tomh 's bimacs on 7/19/22. I ordered a "small" individual, but was pretty shocked how big he was when I received him 😂 (this is coming from only previously owning 2 dwarf octopi haha). He came in very healthy and acclimated quickly. He took freshly thawed...

    Octopus Not Eating

    Hello all, I have a bimac octopus in a 55 gal, who hasn't eaten for a few days, as far as I can tell. I recently did a water change, but the nitrate levels are still a bit higher than I'd like them to be. My octopus has refused it's usual shrimp, and doesn't seem interested in food that I give...

    Live Food Parasites

    Hello all, I have a young bimac in a 55 gallon tank, and I had a question about live food. How concerned should I be about potential parasites on live food? Is there any real risk of transmission of parasites, or is it okay to get live food from some place like h-mart or a local seafood place?

    Seeking octopus

    Hey! Been researching and collecting supplies for awhile now and I believe I'm finally ready to start my cephalopod adventure. Only problem is I cant find a bimac for sale! Everyone is sold out and links from a decade ago are no good. Anyone know where I could get one?

    tank size for hatchlings?

    Hello! I'm working with Octopus bimaculoides and looking at trying to rear some fertilized eggs. I would like to raise them in different tanks than the adults are housed in for logistical reasons (mostly to prevent them from going into the filtration system, but also to better track their...

    [Octopus]: Hank the Bimac

    This is me and my boyfriend's second Bimac and won't be our last. As stated in our Tank Talk post we accidentally acquired our first one from a wholesaler who mislabeled it as a Pacific Dwarf octopus but neither of us had ever owned one or knew of anyone that had kept a cephalopod before so we...
