Foram or not foram?

I have these all over one rock in my tank:



My initial ID is a Foram of some type? The Red Tree Forams I've seen are much brighter red, these are almost purple. Many of them have a very clear branching structure, and I've seen a few with hairs on them...

So did I luck out and get a LR encrusted with forams, or is this simple coralline algae?

Thanks!

Forams buddy

Homotrema rubrum or something like that

 

if by foram you mean foraminifera, i doubt it, as those forams are microscopic (at least from what i got off wikipedia)

i've got the same thing on some of my LR, and it comes and goes. i think it's a form of sponge that my angel eats.

 

i stand corrected. nice id.
here's a link to a reefkeeping article about forams. interesting!

I started adding DT's and these things are going nuts. They're not harmful are they?

 

Not at all.
