Does anyone know of a good resource for finding out what corals can tolerate each others stings? I've read that you can put Hammers and Fine Grape next to each other and that different types of mushrooms are ok together. I have a Torch that is getting close to some Duncan's. Will these two LPS harm each other? I also have a Hammer that is getting a little close to some Acan Lords. I've got a lot of LPS so it would be nice to know what I can group together without worrying about sweeper tentacles.
