My 75 gallon reef tank is four months old and I noticed one of the four heads on my kryptonite coral looks like it has been eaten.The skeleton is exposed. I have two ocelaris clown and one Helfrichi firefish. I have no crabs and only snails. I have live rock so it might be a hitchiker that I have not seen. I was even thinking maybe salt creep, but I am not sure what happened to it. My question is there anything I can do to save it or do you think I will lose it. My parameters are all in check. My two zoanthids, devils hand, toadstool and purple frogspawn all are fine. Nothing else has been changed in the tank. Any advice would be appreciated.
