it is extremely hard finding the information i want on this website. no offense, it is a great website. I live in california, and i want a cuttlefish more than anything, but it looks like all i can possibly get is a bandensis. so can someone tell me the tank size, what they eat, and how much it will roughly cost me each week to keep this awesome creature alive.
