strange pods???

[kuatto]

just noticed these tiny(1mm)blackish balls with what looks like red worms poking out of them,anyone have any idea what they could be?
in the tank is live rock,green mushrooms,tiny featherdusters,sea-urchin,and small racordia(think thats how to spell it).they seem to just appear out of now-where.

Well,after the lights went out i got the flashlight out,and out they popped!Bristlworms.I know most people hate these things,but do they do any good in the aquarium(like keeping the sand free of waiste/food)or do they gotta go?Also what can i put in to eat them,to keep them under control?

the tank is 44corner already 7 small fish,don't have much room for any more fish,so would have to be some kind of crab.

Bristle worms are good. Don't have to worry. It's all part of healthy sandbed fauna. And yup they eat uneaten food and waste.

I don't mind little critters like them,just didn't know if they would harm anything(foregot to mention i have some mushroms+ricordia+tiny featherdusters)I guess getting liverock is like a box of chocolates,you never know what you're gonna get
Still wouldn't mind adding a crab,just don't know which one would be best.
