Hi there, I'm Dane. I recently acquired a 180 gallon tank (6'x2'x2') and I am hoping to use it as a octopus tank. I've wanted one for years and I think I'm ready to take on the challenge. I am working on cycling and establishing the tank currently and while that is happening I am researching types of octopus and their behaviors. I guess I'd be curious on opinions of what species I could go with for a tank this large. I would definitely prefer something that would come out during the day and be semi social and playful. Of course I know these traits can not be guaranteed and from my reading it seems hard to guarantee the species. But any recommendations on a species that might fit in those criteria. Any help or links to more info would be fantastic. Thank you so much, I look forward to my new friend!
