Placing the frag like cosmic says on its size is good. They get a lot of encrusting before taking off upwards. The only down side I have personally found with this is that it actually takes so much lunger for the frag to look like a little colony normally does. It takes time to shape up even though it may grow faster.
A way around this I found and actually copied from Dr. Mac is to take the rubble rock where you are going to put the frag and make a hole in the middle of it with a drill. Make the hole ever so slightly of larger diameter than the base of the frag to be placed. Then, fill the hole with superglue gel and stick the frag in it. It sould be snug, but not tight since it will shred it trying to get it in. Some of the glue will come out and seal the base of the frag at the surface of the rock. Wait a couple of minutes and then place it in the water.
I have done this repeately with great success. Not only does the frag has a stable glue point so it won't break off easily, but they look right after gluing as if they have nee growing out of the rock for a while since you don't see the glue blob. From the begining, they look like a mini colony.
Obviously, this can't be done with all SPS. It works better with most acropra and montipora digitata, but as it is obvious it will not work at all with montipora capricornis and such.
Hope it helps someone else too. I'll try to find a couple of pictures.
