Sorry I didn't see this thread until now. The stargazer I got from you is still holding it's color as when I got them from you. I have them low on the sand bed with 8 bulbs of T5. You can see them below.
What light did you have yours? How much light did you give them?
Nice collection and they look like they are growing well. Mine are in extreme light. They are directly under a 400 watt 20K Metal Halide and about 8 inches into the water. The tank they are in is the SPS tank which of course has high light and high flow.
