Jason, the first time this happened to my GSP I thought they had died for sure. They were perfectly healthy one day, and the next day, they didn't open... and stayed closed for about a week. it seems to be a normal thing; several days later they opened up like there was nothing the matter! So, don't worry, they'll be back! May take a couple days, may take a week! But they'll be back. (unless you start to see crabs crawling all over them, picking at decaying tissue!!!, with evil, foul smelling, putrid... ur..ah... I get ahead of myself... they'll be fine!)
