Salt and vinegar aptasia?
 

I had about 10 aptasia in my tank at 330 this afternoon. I gave them a shot of Heinz pure white vinegar and they shriveled up but looked like they could come back. About 45 minutes ago my Foxface sucked 2 out of the rock and ate them, 20 minutes later my wrasses were fighting over the others as they ate them.Right now there seems to be 2 left,one in a barnacle and one small one that I forgot to dose.The only other thing I did today was a 10% water change a couple hours after the vinegar treatment. Anyone else had this happen?
