rics closed for 2 days now

[gusto1]

I purchased a ric about a month ago, and it's been doing great just the past to days it hasn't opened all of my parameters are good. do they do this often. I have plenty on the same rics on the same rock that are opened and looking fine.

Thanks

anyone?

what do you mean by saying its closed? normally they close when they eat. Do you have a picture?

[gusto1]

I'm terrible at taking pictures, I guess closed is the wrong word, I mean shrunken, sometimes I see it like this in the morning when the lights first go on, but then it expands.

normally it means its stressed. It could be many things. Try moving it somewhere else. I know in my tank when that happens its due to not enough light.

What params did you check and what were they at? Mine would close with nightly pH swings before I had a refugium. Like currentking said, they could be stressed by a lot of things so its good to know what you tested. Did you add anything to the tank (livestock or equipment)?
