My goldfish has taken to do some strange things at night.... he/she swims upside down! He does a lap of the tank and then casually rolls over and swims back. He doesn't do it on a regular basis, seems to be just at night, around 2am..I'm only up at this time to get a drink! It's perfectly healthy, just has this thing about swimming upside down...maybe it's asleep? My clown loaches sleep on their back but goldie swims...very funny to watch.
