My tubbs have done this from time to time as well. They are doing just fine, so it's probably nothing to worry about if you parameters are good. Another thing to consider is nudi's. Look closely at the polyps and look for any type of pest that might be bothering them. They will be the same color of the polyps they are eating so they are sometimes hard to spot.

i thought about some type of pest. thinking of doing a dip. wouldn't pest be affecting my other zoa frag's

Mine just did this, they closed up for a few day and they now are beginning to open up again.

so my blue tubbs are not opening still. i pulled frag out to get a better look at them. noticed tiny white string like thing in between polyps. used tweezer to try to remome one. it streched and would not pull free. tried several times, and it finally broke free.have some pic's but not that great

here they are in better time's

[SIR PATRICK]

Blow them off w/ a turkey baster.

Dip with Lugol's.
Make the colony clean and return to the system.

tried baster no help.

dipped them in "REVIVE" twice now in then last three weeks. is this enough dipping or should i be doing it more often,and if so, how often?
also should i be using another dipping solution, is there one that's better than the others?

thanks
