Small red things on frogsspawn coral

[lstimpy]

Noticed a few of these tiny red branching things on the stalks of my frogsspawn coral. Half of it won't open fully... Any one know what they are and if they're bad? Thanks!

I cant really see it in the picture. Does it look like algae?

I'm gonna go with foraminiferans.
