When your SPS colonies start to grow together, do you let them fight it out or carefully prune them to keep them separated? What do you do when SPS starts to reach the glass.....let it grow or frag it? I have both plating and branching montis that are overtaking my tank. I have been breaking off pieces to keep them from overtaking other (more expensive) colonies (which often ruins their appearance...I much prefer the rounded plates rather than jagged edges where I broke it off). Would you just let them grow together and see which one wins or continue to frag? I can't really tell how aggressive they are since I haven't let them grow together too much yet. They did grow around some zoas to the point where there is just a small hole in the monti where the zoa pops up through when the lights come on lol.
