hello everybody! i needed some advice. im thinking about getting a 75gal hex. do you think it would be a bad idea to put a cuttelfish (the bigger kind) in? i would really only feel comfortable putting one in nothing below a 100gal. im thinking that it might be better for an octopus? but i was wondering if cuttels feel more comfortable in deeper water or if they like to have more room to swim and jet back? thanks for any thoughts!
