hi all. I am looking at getting my first octopus, it's safe to say they're what got me in to the fish keeping hobby 6 years ago although I wanted to start with the basics and build up to keeping one. I've done a lot of research over the years and I think I'm ready to take the step, I've got a 225litre tank lined up but I'm stuck on the best species, all the research I've done has pointed to the bimac given their daytime habits and overall size, although I'm not sure how common they are over here in the UK. My local fish store has said they can easily get hold of zebra, vulgaris and macropus, although I don't know much about them specifically their size and habits (are they mostly nocturnal?) I've read that zebras don't do very well in captivity and that they are quite expensive. Can anyone recommend one that will be good to keep that would be suitable to a 225litre tank? Should I keep trying to source a bimac ? Thanks in advance!
