yeah well it's a massive tank. If I'm not mistaken they also house one of the world's only whale sharks in captivity. Good luck trying to re-create those same conditions in your home.jimmybling31;3436141; said:at the tennessee aquarium they have a large school of peacock bass with a school of piranhas. the piranhas tend to stay towards the back and the peacock bass were right up front looking for attentions. they also has a few plecos in there with them. the plecos were very large and didn't seem to mind anyone.
