The first thing I am going to as is,
What have you done differently between the before and after pictures.

I have lots of Tips to Help Save Your Zoanthids in the Above Thread.

Check for zoa eating nudibranchs. That flatworm exit should take care of it if it is the nudis. But remember to do it a few times since they lay eggs. Check for little spiral eggs on the zoas. And get carbon. Once the medication is completed, add the carbon.
