Sorry, getting sidetracked it's a Leptastrea pruinosa, fast grower It'll develop deep purple skirts and green eye's if kept under indirect light...Leptastrea's are one of those corals that a lot of reefers skip over, this one is nothing special but nice colors. Once you start looking around you see that there some incredible colormorphs, easy coral to keep IMO.......

The frag you actually have is a test frag to measure growth and color vs placement in my frag tank. It was also a test frag to determine the best way to frag a LPS like this. I've used hacksaws, screwdrivers, razors, knifes, hammers and just about anything within grabbing reach..LOL..Almost impossible to kill IMO and thrives on being fragged....If you could do me a favor and let me know what happens to this particular frag, color, growth etc.

Here is the thread on the actual fragging of the leptastrea you have along with pics of the mother colony.
