hi does anyone know if the marginatus or the cyana are pygmys? thanks.

O. cyanea isn't a pygmy by any means. I believe they get quite a bit larger than O. vulgaris. O. marginatus is a relatively small species but they aren't a pygmy either.

cyaneus could work out well in an absolutely HUGE tank, since theyre diurnal

Yeah, they're probably my favorite from all the footage I've seen. Very impressive in just about every way an octopus could be. If only I could transform a bedroom into a tank...:snorkel:

Is someone sellling these species?
