Closed zoas
 

My zoa's never really open up they stay mostly closed and seem like they r shriveling up and they just keep getting smaller till there is nothing left. What would be the problem and what can i do?



Thanks Daniel

what are your parameters, are you dosing anything? do you have any fish that nip? have you noticed anything crawling around on them>?

Well parameters are all good but i did see a black crab walking around at night.
was going to put a pic of my zoo`s but i cant figure it out lol

Look up zoa eating nudibranch. They can be hard to see unless you know what to look for.
