*Sprt sprt!* My mom's always thought about having a saltwater aquarium full of exotic fish. Recently, I purposed that we go ahead with preparing a tank, learning how to set things up, etc. I then asked her if I could get a squid or octopus (my original intention was that I like cephalopods and I wanted to see how intelligent they are, i.e.- teach it to shake hands or whatever) for the tank. She agreed, but only if my grades next semester were good enough. So, I need to know from some experts, which is the better and/or more intelligent cephalopod to have: a squid or an octopus?
