I got the feather duster today and put it in my main tank. found a perfect spot for it that was away from where the shrimp hang out. Well after about 2 hours the duster is gone and one of my crabs has ahold of it. It took quite a bit of effort to get the crab to release the duster but after shaking it quite a bit and droping it it finally released it. The duster now has a new home in my sump. It should be fine in there, just wont to get to view it like I would have if it was in the main tank.
thanks
Jeff
