There's a show on the discovery channel in Europe called Jungle Reels about a guy who gos fishing for arapaima in the Upper Amazon. I can fully recommend this to anyone who wants to see a lot of very big fish (up to 4 metres) in their biotope. Lots of very big arowana, red tails, cichla and some astoundingly nasty looking pim catfish, as well as comparatively tame piranha, pacu, timbacu and cichlids. Plus arapiama.
