I love zoos, they are one of the few soft corals that come in soooo many color Varities!... But I have a question, I just moved mine, they are brown with a neon green center, and they are reallly taking a long time to get back to how they were before.. I moved them just slightly upward a bit... about 3 inches up from before! and its been 4 days now and they still are open like they were... why is this?
