[hnav94]

Local fish store is closing and they have these on a rock in large display but none of their employees have any salt water experience or know what these are, doing a little research before I try and buy em before store closes forever

Sinularia brassica possibly, based on the visible sclerites

Yes to Sinulara, aka Cabbage, also Green Leather by some vendors. It's a great sift coral.
