Incredible stuff!
A few years back I went to Hamburg and also to the Berlin Aquarium, I had totally forgotten about the banana thing until now!
One of there marine bio's told me that they also fed banana's to there open air natural 1000gl tank as well.
I wonder if my fish would like a banana split from DQ as there on sale right now
I only wonder about pollution
Will try to post a pic of that tank if I can dig it up from the archives
cheers, Rich
