At the aquariam at the Wilhema zoo in Stuttgart, Germany... there were 2 or 3 of them in the tank in question. They were like spheres, except compressed sideways (so 3d ovals)... orangish with white stripes or spots IIRC. No easily discernable mouth/fins (and I'm not sure if what I thought were eyes were in fact eyes). They were just floating in place - almost compeltely stationary. I think they were about 5" tall and maybe 3" wide, maybe 4" long (?) but the water may have distorted the size.
The Wilhelma website doesn't even seem to acknowledge the existence of an aquarium there. Any idea what these fish are called?
