Had it for 5+ years . It started as a 2 inch frag. I have sps and LPS everything else is doing great . Sps have lots of polyp extension. Just this one toadstool is looking bad. This piece used to be over 12” when it was happy. Any ideas or advice? It had full polyp extension a week ago.
It's still alive and leave it alone. Toadstools will periodicly close up and it's best to be patient. Messing with it can just be a source of stress for it which would only motivate it to stay closed longer.
