Hello, I am having a problem with my sebae anemone. I only had him 2 weeks, and he's been fine until 2 days ago. He went under a rock and shriveled, and has not expanded since. Today i placed him back up top where he usually stays, and took pictures. Any ideas what's going on? I have a 30 gal aquarium, all the water paramaters and salinity are impeccable. I am using a power compact & actinic lighting. Any help or advice would be great, as i'm new to the hobby. And sorry about the quality of the pics.
