Brittle Starfish

[fishmanty]

So my 2 to 3 month old tank is coming along well. Its a 28gal JBJ cube that did have the HQI but I changed it over to LED. I have got some various corals and a couple small anemones in there. The rocks I bought have a great deal of brittle starfish in them, and its starting to get to the point that they are reaching out of all the holes in the rocks and covering my Zoas, xenia, and even my littlest RBTA (3" diameter at its best).

Im heading to Edmonton this weekend (From Lloydminster, hitting up the city for some things), and want to consider a Harlequin shrimp to annihilate this issue.

My questions are:
1) Does anyone know anywhere that has a Harlequin in stock right now in edmonton?
2) Would annihilating the starfish population reduce my ability to handle waste by enough to be worried about?
3) How easy is it to lure out a couple starfish and cull them?
