What are these things!?!?!

[hobomoe]

So all of a sudden I'm getting all of these red things that are coming from my live rock. They look like little tubes but as they get bigger they divide. For example: One branch splits and divides into 2 then that turns to four and the things keep getting larger.
Now they are taking over my live rock and I have no idea what these little red tube like things are, they're not creatures. HELP!

Well if you remember looking under the microscope at Amoeba, they are basically like Amoeba but with a shell. Some are free floating, others grow on surfaces like this. When these sorts of guys (like the common Homotrema) die and break off, they contribute to the pink color of many beaches (and others that are white, I might add, also form calcareous sediments).
I think promisetbg gets the prize for this ID! Sounds like a match at least!
