Help! Can someone ID this?

So I am new to reefing, been keeping fresh tanks for 11+ years. What in the world is this? It started growing on my live rock, not the Aiptasia :) also if the pic is clear enough maybe what type of clam I have as well? Thanks!

If it was live FL/Caribbean rock, it's probably Favia Fragum or Siderastrea Radians. Common stony polyps that grow on LR.

Thanks! Will it always be brown and funky looking?
