I'm toying with the idea of looking into cuttlefish. I really am trying to gather all the info I possibly can about them. I can't seem to find the answer to a big question I have. I can find tank size, but not ideal tank dimensions. Would cuttles do well in a tall tank? I have a 56 that was set up for a while and due to moving issues, is now distinctly empty. I had plans to set up another reef, but the idea of cuttles sounds much more interesting. The tank is a 56g tank, but it's tall. Dimensions are weird: 30-1/4"L x 18-1/4"W x 57-7/16"H. Would cuttles thrive in a tank this size or would they prefer a longer tank. I feel like they seem to spend a lot of time on the ground, so my gut says maybe not, but it never hurts to ask.
