Reefing newb
Came home tonight and on one of my rocks was a half pink and half purple worm. It was very hairy looking. Tried to get a pic but it was gone by the time i got back to the tank. Not sure what it was and was hoping you all might have an idea. Should I be worried? I have read brisstle worms are bad and need to be removed but i cant find a good pic of one that looks like what i saw. Any help?
