Hey,
I have two goldfishes, one we have had for around 5 years and have lately moved into a small tank, rather than a smaller bowl. The new tank has the is more decorative with stones and plastic trees. Last week we found it curled over on one side, not moving at the bottom of the tank and it's gills not moving for minutes before it would start to twirl and do backflips, (so to speak). We googled it and decided it had all the symptoms of 'Swim Bladder', ringing the nearest fish store, I went to pick up some water treatment which within hours of application made the fish look like it had never been ill.
