These guys have all been in the tank for about one and a half months. The purple one on the left started staying closed about a week ago. It isn’t completely closed, but zero polyp extension. I broadcast feed ReefRoids, phyto and aminos once or twice a week and twice daily feedings that have lots of tiny parts to it. The left one has much longer tentacles than the other two. I thought maybe there was too much current, but it’s not like constant current. It’s fairly random where they are. Also, the big pincushion urchin was grazing around them Last week. Not sure if it might have pocked it.
should I be concerned or is he just mad about something and will eventually reopen.
