Hi everyone. I finally found a octopus at my horrible LFS today, so I jumped on it since he was small "mantle little over an inch". The temperature now is 75 degrees, but my question is how can I be sure he is a bimac so I can lower heater/buy chiller if necessary? The people at the LFS were clueless as to where he came from or any other info, as usual. I put a youtube video up of him, which is pretty bad quality, but it may help you a little. He is in with a few corals now, which I will relocate to my basement reef tank. He did display the unbroken blue ring below his eyes, as bimacs are supposed to. I also noticed after an hour being in he pulled a bumblebee snail into his little den and ate it! Thats a great sign. http://www.youtube.com/watch?v=FxEhhm2ByfQ Look forward to hearing from you guys and owning my first octopus, finally... after years of searching.
