Help Me figure out what happened to Zoas
I am trying to figure out what happened to these Zoas in my reef. This rock was looking good last week. Then I noticed that it looked like the polyps were retreating. It has gotten worse. Any thoughts on what might be causing this? Do you think they might come back ? This has happened - once before. The water tests are OK - nothing out of whack there.
This is a 150 gallon tank - there is a Coral Blue Angle and a Flame Angle in the tank. I have not noticed them nipping on any coral - I do see them nipping on some of the rocks. Perhaps they are doing this at night or when I am not around. There are 2 Emerald Crabs - I hardly ever see them. The work at night. There are some blue and red leg crabs. Thoughts ? Thanks Bruce |

my vote is for the crabs. did you buy live rock or base rock you could have a hitchhiker you may not know about yet. in my experience angels only nip at hard corals.

I had a rogue Bi Color that went nuts on Zoanthids.
I ended up draining the tank to get it out. |

There's been some accounts where emerald crabs have been caught picking at zoanthids as well.
Check this out. http://www.reefcentral.com/forums/sh...d.php?t=632970 |

Emeralds are real hit or miss... I have had some that are innocent as can be while others were opportunistic hunters lol.
As for the Angels - you can bet your rear end they'll make a snack out of your zoas. But they sure are pretty lol.

Thanks for the input. Yes I have more fish in this tank - but none of them seem interested in the coral or Zoas. It would be tough to catch the angles. Could try late at night.
