I've considered purchasing a piece with red to add to my all green one. Did you give the new piece any special acclimation time before letting it come into close contact with your existing pieces?One thing that Eddie didn’t mention is that the frag he got from me had just one small red spot. He can confirm but I would say it was about 1/6 of the coral. Now red is popping up in the middle of green or gold areas. I actually purchased a piece back from him and grew it into one of my colonies to see what would happen. Results are pending…
