I know Acroporas can be mounted very close together, but is there an "ideal" distance, so when they are fully grown they look nice? I see a lot of tanks with tons of frags mounted all over the rocks and it looks like it will look really crowded by the time they all grow.
I was just wondering if there was a rule of thumb as to the distance I should mount my frags.
