I had 2 separate frags of horizons, at least 8 polyps on each. Both had been in the tank, open and appeared healthy approx 2 months. On the same day both frags closed up and over the course of about 2 wks melted away. All the other zoas and rics (approx 12 frags of differing types) in the tank appear fine and are growing. There had been no changes to the tank or water quality as far as I can tell. Any ideas about why it would happen?
Pic of tank, you can see one of the closed horizons in the center. That frag is now bare rock.
