what is this? bad or ok??
 

So i have this frogspawn and i really like it. It had a piece of kenya tree growing on the bottom of it when i bought it so i just ripped it out. but i have noticed in the last month a bunch of polyps on the base of the rock.. is this a bad thing? im worried, it almost looks like baby aptasia. also there is this white fuzzy stuff that is growing up the branch of the frogspawn.. any help on a id would be really helpfull thanks guys

Looks like colonial hydroids.

what the hell is that? the polyps or the white fuz?

Those are the little brown things.... They are harmless unless you jam your thumb down on one...they are like little needles.

you sure they are harmelss? if is colonial hydroids everything i read says they are bad! :s

also if i touch them they disapear and seam to be soft?? in like a clear tube of some kind???

+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 :(
