Ok so I know some bristle worms in your aquarium is well a good thing... But we have an abundance of them and I was wondering how we might lower said population any suggestions would be greatly appreciated... Also my wife is currently trying to get a picture of it but we have something that has attached itself to a small piece of live rock that has camouflaged itself to match said rock its about the size of a shell and looks like it has a mouth (opens and closes it) its not a bi-valve or a muscle the creature appears to be soft but does not move and we would have not noticed it if are hermit crabs weren't trying to attack it every time we turned around i will try and get a picture of it and post it but does anyone have any suggestions on what this thing could be??
