European sturgeon - Donaustör

Two weeks ago there was a big Aquarium on the Main Square in Linz with a variety of fish that live in the Danube. A lot of children and their parents were gathering around and watching the fish swimming around in the big tank of water. I also found it very interesting and took some pictures with my smartphone since the water was a bit dirty it was not easy to take some nice pictures only when the fish came extremely close to the glass and was visible very good.
