Coral Compatibility

[liquid wind]

I was listening to one of the podcasts and I heard as an example about two corals being incompatible euphillia i think. I was wondering how many different corals are incompatible. I always thought you could stick as many corals that could fit in the tank (given their individual conditions are met and they don't touch). What corals aren't compatible?

corals in some cases will eat other corals close to them...i dont remember the species. I has a sps frag fall into a torch...it got torched

Euphelia are interesting in that hammer nad frogspawn can touch each other, but torch 9in the same family) can not touch either of the others without them stinging each other. Most corals should be kept ftom physicaly touching each other as one will usually kill the other. As far as being completely incompatible though, nothing comes immediately to mind. I know leather corals are pretty noxious and will emit chemicals into the water that stunt the growth of other corals (notably SPS), but there are plenty of tanks out there with leathers and acros in them. They seem to be fine as long as water changes are kept up, and I know a lot of them run carbon to combat this chemical warfare.

I'm not sure if "eating" is the correct operative word here. "Killing" might be more appropriate.
