raddogz, once I read the method others have been using, I'll decide if I go that route. I need to know more, like what species they prefer and which will they ignore - do they like Acropora millepora, for example? I have a tank full of those, and they look perfectly happy.
It would be nice to figure out where these came from. And what they tend to hang out upon, as I have a prop section full of corals. Would they hitchhike on zoanthids and leathers, for example, or do they tend to congregate on SPS only, and then which kinds specifically? I've never tackled this topic because it wasn't something I was dealing with, so I'm going to have to do some homework.
I wish I wasn't so busy work-wise right now, because I'll need to dedicate some time to this obviously.
