My fantail gold fish hasn't been acting like his energetic self lately and this morning I noticed a bump on one side right behind his back fins...that side doesn't seem to be a maneuverable as the other side. He's sitting at the bottom of the tank and not doing much at all. Any idea what's wrong with him?
pics would be a great advantage for someone who may recognise the symptom, a description of a bump is not very helpful, may take a while to get a good pic
