So I was dipping some coral about 6 months ago and mini brittle star came off, and I thought hmmm I hear those are good lets save it and add it to the refugium.  Fast forward and I have MONSTEROUS amount of mini brittle stars in my tank.  I can't figure out if these guys are bothering my zoas or not but they are all around and in them.  My zoas have not been growing great lately and I am starting to wonder.  Does anyone else have huge numbers and suspect they are bothering things?  If I were to get some natural control would you recommend a wrasse, a harlequin shrimp, or a dragonet?  Here is a picture of my vacuum tube during a normal water change.
