Too close!?

[River2sea]

Is it possible to be keeping corals to close together? Are on the same rock? And I also have a bubble tip anemone that I placed last night and it moved and is partially on the base of a frag.

Anemones can sting and kill your corals just like corals can sting and kill each other. Some corals can touch, others can't. It's an important thing to look into before placing a coral somewhere in the tank. Are there specific corals you were thinking of placing next to each other?
