In St. John's they have a really unusual aquarium, called The Fluvarium. It's essentially windows into a stream with salmon and trout. It's not, if I'm honest, the best tourist attraction, but it can make for some fun fishy photos!
The world’s oldest living aquarium fish is actually even older than scientists initially believed.
According to an analysis by the California Academy of Sciences, the Steinhart Aquarium’s beloved Australian lungfish named Methuselah is estimated to be about 92 years old, with a high-estimate of over 100.
Popular Science reports that "Methuselah first arrived at the San Francisco aquarium in 1938": https://flip.it/Vgu_DO
Oxygène ! Dans la journée les plantes absorbent du CO2 et rejettent de l'oxygène. C'est aussi le cas des plantes aquatiques : il est donc possible, dans un aquarium, d'observer la photosynthèse "en direct" grâce aux jolies bulles d'oxygène qui apparaissent un peu partout. En fin de journée l'eau est saturée d'oxygène et de plus grosses bulles restent coincées sous les feuilles, formant un paysage scintillant. #aquarium#Oxygene
