LPS gurus... can these touch at all?

[lastlight]

Thanks for the advice mindy. The rock is big enough that I may just give each piece equal spacing on the sides and let them grow. then down the road if they fight i'll have something to save since they're bigger.

i'm a bit scared to just place them together but maybe tonight when I have time to sit in front of the tank. Although the two pieces on the left already are touching (within 1mm) so maybe that test has already been passed lol.
