My lips are moving but the words coming out aren't matching the movements..... You kill my sista, you kill my fada, now you face my shaolin style!
As for the stocking, just put a tiny bit of food in there and that should be enough to attract a bristleworm. One way to prevent your fish from being injured in it is to put a piece of pvc inside it or even a jar or something to keep the nylon stretched out so it doesn't act like a net and catch the spines and fins and possible gills of your fish. They should crawl right in at night and you'll have them. They also sell bristle worm traps which are basically funnels on the end of a tube, but they're really small and for really small bristle worms. You could probably use the same system, though. By the way, you really shouldn't take all of the fauna out of your tank, even if you think you have a lot, you can always use more.
