100s of Brittle Stars

[hulashaker]

I joined recently and have been learning lots from what I've read, so thank you everyone for sharing..........it will show to be a great benefit to me.
I've had an incident a month ago where my stepson's friend was sleep walking and accidentily fed my tank a whole container of fish food..............not good, lots of death- total mayhem. My clown fish, hermits and snails and corals survived Just getting confident all is alright to add anew I have, it seems, billions of brittle stars. Everything I read is that they are pretty much- a good thing. But all my live rock has little legs scworming out of every crack! Does anyone have any info or suggestions on how to get them under control. I"m not to impressed with the look
Thanks for your imput in advance, I look forward to getting these &%$^#%^*s under control !
