Torch Coral Proximity

[twenty12]

So I have read alot about torch corals and how they can be aggressive. That you should leave space between it and other corals. I have two questions based on that.
1. Will a torch coral be aggressive to zoanthids?
2. How do you determine the safe distance? If mine is about 1 inch in size how far away should other items be?
Here are two pictures. The zoanthid is a little closed cause of the snail that hit them when I took the picture.

Yours is pretty small now, but with proper care it will grow larger. I would say to be on the safe side I would leave about 3 inches all the way around. Less room on the upside of the current.

The distant that they are at now is fine, just move things when it grows. I've got torch's, hammers, frogspawns, grape corals, I just make sure they are touching anything when they are fully open. So far so good.
