These are awesome displays. I recently visited the Stockholm aquarium and the Paris aquarium and I was disappointed that the Paris aquarium did not have more freshwater displays. They did have a 160,000 gallon salt with a lot of sharks though. The Stockholm aquarium however, had a lot of freshwater including piranhas, pacus, oscars, a silver arowana, discus and RTC. It looked similar to the above pics with a lot of plants. I have not been to a whole lot of aquariums but it seems like most of them focus on saltwater. Why not more fresh? There are so many cool freshwater fish.
