Help with ID - Pests!?

[dcal1985]

A few of my corals have been acting cranky lately and the parameters are all good with no major changes. I pulled them for an inspection/dip and found these. At first I was thinking vermetids (which are definitely present) but I found these structures as well that are soft. Any thoughts?
