Ok, would I be able to keep live corals with a bimac?

Well, the Bimac wouldn't eat the corals.....but octos like to rearrange their "furniture" so to speak, so if you don't mind the risk of the corals being crushed, it can be done.

It would be difficult with a bimac because they do not live at tropical termperatures. It would be good if you could lower the water temperature to the low seventies.

Then, no stinging corals and no bright lights. How about some mushrooms? Don't put any coral in your tank that you're not prepared to lose because an octopus might run over them or turn them upside down.
