I've browsed many of the pages to gain some info about getting an octo, but still have some questions I either cannot find the answer to or found the answer to in many of the discussions but forgot and don't know where to look again. First off, my tank is ready for an octo. There's plenty of live rock/sand. All that remains in it is a snail, some hermits, a cucumber, and a damsel (I've removed all my other inverts/corals). I've been reading up as much as possible as far as which octo to get--seems it's either a bimac or a vulgaris. I've noticed that the majority have bimacs or at least recommend bimacs...Is there a reason for this? Obviously, I would like an octo which wouldn't constantly hide in the live rock, but interact (during day and night). Do bimacs offer this compared to a vulgaris? Another question... would getting a tank-raised octo be preferred to one caught from the wild. The LFS near me has a baby vulgaris that was "most likely" caught from the wild. Does one acclimate better than the other? Would one likely be more active in a tank compared to the other? And as far as feeding, do tank-raised better take frozen food compared to wild caught? When I do get an octo, I'll be taking the damsel out, but wanted to keep the cucumber in there. Is this OK? Also, can any other inverts/corals be placed in there at the time the octo arrives? Hope no one minds all these questions...and I'm sure some may overlap questions previously asked, but just can't find the answer for. I just wanted as much info I can get before actually getting the little guy.
