Guys what is happening to my hammer coral? It was perfectly healthy yesterday and now half the skeleton is showing!? My other hammer looks great.. they’ve been in the tank for two months!

Dang that’s scary fast. I’d check alk and flow first, and maybe move that hermit if it’s been irritating the tissue.

Parameters all look great, they’ve been under the same flow for weeks and have grown x3 in size since I first got them so I’m very surprised. Only thing is my calcium went from 440-480ppm but this was gradual over 1 week. Water changes done every week, and the hammer looked great last night and this morning. Something nearly killed it over 8 hours
