Octospawn to close to duncan?

[nystang]

My duncan grows pretty fast and almost touch my octospawn ( Euphyllia yaeyamaensis). Since those two corals do not belong to the same family or genus I'm afraid once the duncan's tentacles are long enough the octospawn will be hurt. Is this the time to frag my duncan (it has over 25 heads)? It looks pretty awesome so I would like to keep it for some time and moving it is out of the question.

most likely the euphyllia will be doing the damage .ducanopsamia are very mild mannered and their tentacles don't pack much of a punch. Euphyllia on the other hand have strong stinging sweepers.
