I got a acro frag a few months ago and the polyps have been out all day everyday since I put it in the tank. The only time they retreat is if I touch the coral. It seems like it would be a good thing to a new guy like me, but I just was curious if it could be a sign of something they are lacking like not enough light?
Bragger! Some acros are almost always extended and some rarely all. It means he's happy and hungry. Good water quality and lighting are the keys. In honor of spring training......
