to TONMO!
The best place to start is the "Ceph Care Articles" at the upper left of the navigation bar at the top of the page... In Hawaii, you're more likely to find
O. cyanea (often called a "day octopus" in hawaii) than the ones many folks here keep on the mainland, but I think they generally have the same requirements (although they probably want a more tropical temperature.) There are some people who have kept
cyanea around, although I don't think that anyone has one now, except some researchers perhaps. There are several lists in those articles that can give you a good overview of the needs and requirements for keeping an octo in general, and
cyanea has often been kept for research, so there is a lot of knowledge about them, so it seems like they're a better bet than trying to import one from the mainland. I'm not sure if they get significantly bigger than bimacs, though, so I'm not positive whether a 55gal is appropriate, but I have some recollection that we've had people keep them in 55gals successfully...
