Hello. I'm a sophomore in an advance biology class at my high school. For a project, my teacher wants us to raise and take care of an invertibrate of our choice. It could've been anything from a sea sponge to a fiddler crab, really, as long as it was procured legally. I decided on some form of an octopus because frankly, they've always fascinated me. Now this puts me in a bit of a pickle because I really know nothing about how to get an octopus, or pricing, or anything of that nature. I need some guidance. Here's what I'm looking for: -A relatively hardy creature (something that won't die easily while I'm still learning how to care for it) -Somewhat small as an adult, but still larger than a golf ball. Now, on that, what species should I get, and where would I get it? Also, what tank size is best, what's the best food source and environment? Those kinds of things. A general estimate of total price would be helpful too. Any information you guys could find would be fantastic. Thank you!
