I've only owned 1 tahitian B/F, but I have a atlantic longnose and a banded butterfly that don't bother the octo's. I can't collect corals, so I don't know what the banded would do, they are coral eaters in the wild, in fact most don't survive in tanks, but this one was tiny and I raised him so he grew with no corals and on frozen aquarium foods.
As a general rule, the longsnouted butterflies are the most well behaved in tanks, they usually use their long noses to pick benthic inverts from between the coral branches, that is why they have such long snouts, so they are more reef safe then the others. There are also a group of planktavores such as the heniochus and pyramid butterflies which are more safe then the main group of butterflies.
