I have some Emerald Paly's that were open and growing like crazy. The last couple days they have stayed closed. Is there something I should check? All my other Zoa's and are fine. My leather is also not extending like it was. I added a LemonPeel Angel and I think he has picked on the Paly's a little. I did a water test and everything is good. I dont have any unusual readings. I will be doing a WC tomorrow. Any ideas?
