today my orange plate coral has blown up about double it's normal size. is this a normal thing? i've had it about 5 mo give or take. it's blown up once before but not near what it is now. last time it only lasted about 5-10 min then went back to normal. today it's been like this for about 20-25 min and it seems to be blowing up more than going back down. it's little tenticle thingies are now showing, but a few min ago they were not. any advice on this would be great. thanks! jessica
