Hello all. I have started to see these red "things" start to grow on a section of my live rock (real live ocean rock) and I'm curious to see if anyone knows what they are? There colorful and pretty cool, just be nice to know what they are. Attached pics show them in the circled areas, hopefully you can zoom in and see them. Thanks!

Assuming they're hard/solid, my first thought would be benthic foraminiferans like Homotrema rubrum or Miniacina miniacea. If so, they're harmless filter feeders.

Wow, that's great information thank you! They are more on the form side.
