I just got a cuttlefish via my local fish store. I paid $130. I had originally asked the owner to try and get one back in July, but he could not obtain one until now. He only was able to obtain one, and did not know too much about the cuttle's background (age? tank raised? even species?). I believe the cuttle I got was a bandensis. It's a couple of inches long, so I don't even know roughly how old that would make it. Hopefully, it has several more months of lifespan left, but I don't know.
This was the first cuttle I've even seen at any of the fish stores in the area, so I consider myself rather lucky to have even gotten this one.
