Can anyone explain why this would happen. It's been this way for a while. When I first got it, it was nice and full. My Picasso clowns started hosting and all was well and healthy. Over time it kept shrinking and is about the size of a quarter I haven't checked my parameters but will update with it tomorrow. Any info would help. All other corals are doing well. But I have basic stuff. Like Xenia anthalia some zoos Nepthia blue sponge candy canes
