+1 colonial hydroids. I understand they sting corals if they grow close to them. I have them as well and I find they are hard to get rid of. Butane torch works good for the LR that you can take out of the tank.

They are a bastard to get rid of and multiply like crazy! The only thing that I've found to work for me is Sodium Hydroxide. Totally burns them away: nothing left but bare rock.

hmm..im thinking of fragging the frogspawn closer to its base and then tossing the rock... hopefully they havent spread anywhere esle
