My utter choas have had a head or two looking like this. Not sure what's wrong with it.

How long of you had it and what your water parameters?

Have had them since the Cali RAP in October. All my other 5 zoas are doing great that i got from the same vendor. Haven't tested my parameters since the water change on sunday. Never had water quality issues since i started the tank in april of 2017. I can test my water later today. I have had a potters angel in my tank since october. Not sure if it has been botbering the zoas. Here are some of the other zoas i got.

Where are the zoas placed in your tank? Maybe try lowering them.

They were all on the sandbed when it happened. They are happier on my fragrack now since my conches and wrasses arent getting sand on them
