I made the mistake of using foam not made for filtering and all my fish started doing that (shaking head from another thread). I'm sure I poisoned them... I lost one.. it's been two weeks and they are still not acting right. I've changed the water completely, added quick start etc.. they are not eating much if at all but just hoping they are getting food off the bottom. Im freaked out and don't want them to suffer....
