Jellyfish in an aquarium are wonderful to look at, but not to swim with. Ouch!

Moon jellyfish swim in their aquarium at the Sea Life centre in Koenigswinter, Germany, March 31. Five different types of jellyfish are featured under the motto 'Jellyfish Magic' at the Sea Life center.


I live about 15 minutes away from Sea Life Aquarium. Königswinter is on the west side of the Rhine, just south of Bonn. The aquarium is easy to reach with the Tram Nr. 62. Any american visiting Cologne should take a side trip and visit this aquarium. It is worth it. I have taken my daughter there 4 times in the last year.
I remember seeing jellyfish near Long Island years ago that had those circles inside. I wasn't able to see them "glow". Wolf518
