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.
