I have had two different zoo frag colonies that have now disappeared. I have not introduced anything new into my tank that would be the culprit. I have 2 clown's, 2 green chromis, 1 yellow tang, banded shrimp, and some hermit crabs. One of the frags was from the DBTC, purple hearted zoas, the others were a nice brick red and both were developing new polyps nicely. Who do you suspect might have done it?
