the name flamboyant cuttlefish popped out from the deeper recesses of my brain so I googled it and I think that might be the one (Metasepia pfefferi) [ame=http://www.google.co.nz/search?hl=en&qscrl=1&nord=1&rlz=1T4ADRA_enNZ390NZ392&q=flamboyant+cuttlefish&ion=1&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&biw=1600&bih=688&wrapid=tlif133179796972610&um=1&ie=UTF-8&tbm=isch&source=og&sa=N&tab=wi&ei=059hT5T_Dc-jiAe_1oC-BQ]flamboyant cuttlefish - Google Search[/ame]
I think that this is exactly right. This cuttlefish looks like the species kept at the California Academy of Sciences which is the flamboyant cuttlefish.
