Inverted Zoas

[grouper25]

Does anyone know why some zoas remain open but invert their skirts?????? Other zoas in the tank are fine and my parameters are all within reasonable ranges...... Thx

Different zoas have different lighting requirements and some even prefer dirty water. These are 2 possabilities

are they mushrooming on you?

 

[grouper25]

Yes, they are mushrooming........?????????????Seems the skirts just invert. Wierd, cause other zoas in the tank are fine. Water parametrs all within acceptable ranges.

Either they are irritated or predated on by something..

or sometimes they just do that for the hell of it ( beats me sometimes )

Dude, my gpe's do that from time to time and no other zoas in my tank do it.

Ours do the same thing from time to time for a few hours or less.
