I have like probably a hundred brisstle worms in my refuge. Are they good things to have in a refuge? I think, but I am not sure, I think they eat the caulpera. Do Brisstles eat macro algae?
I have big brisstles in the main tank, but i got my refuge stuff from another person. And in there their are a bunch of small ones. I thought they eat algae because some of the caulpera looks like it has holes in it, as if something was eating it?
