Looking on-line I see many photos of reef tanks absolutely full of corals, with no virtually space in between them. At the same time, I have read many posts that say corals fight and sting one another, so you need to be very careful to space them apart. How can I reconcile these two pictures? Is there a short list of dangerous (to each other) corals that are best avoided?
