Cosmocaixa, Biggest fresh water amazon tank, 400 Tons

Biggest freshwater tank i've ever seen which is found in Cosmo Caixa nature and science musem, Barcelona.
I didn't see proper information about volume and dimensions but some people say it holds 400 tons of water.

how do those little fish (red minors 6:48 ?) survive ?

[@r.svispute4558]

400 tons of water would mean it holds about 100,000 gallons. Very nice.

I don't know the exact volume but i didn't see any freshwater tank bigger than this. If someone knows better tell us :)
