Hydrophornia question

[daniella3d]

I had a beautiful gorniopora that rolled at the base of mine and it was digested fully in the morning.

On the other end, I have an alveopora that is right beside it and it is touching it all day long ( but never remain more than a few seconds in contact) and it is not affected. This has been going one for a few months and I see no sign of war or that the hydno is releasing the filaments.

I think in order for the war to take place the coral must touch and remain in contact with the hydnophora.

I also have a gorgonian that is touching the hydno the same way, never more than a few seconds at the time and no harm done. I think it's the permanent contact that is dangerous, especially during the night time.
