Not sure about this Zoa

[Marz]

Hey all, quick question. I have seen this Zoa closed before when the truchus snails get on the plug, but it hasn't opened. Is it something I should be concerned about? All others seem fine.

What are you tank paramaters?? Alk? What kind of lighting do you have? Any noticable pests? Have you tried a dip yet? To me from the pic it looks like it may need a little more light, IMO.

Looks like there may b a small vermitid snail in the forefront...their "webs" will cause ZOA's to close up...

I actually figured it out. Trochus kept plowing it with its shell. I caught him doing it when he thought I wasn't looking.
