Fish Tank Atlas
A browser aquarium sim where you must cycle the tank before fish can live in it
A free, honest way to learn why new aquariums kill fish: you have to grow the bacteria first, and the water chemistry shows the cost of rushing.
Fish Tank Atlas, a free freshwater fish-care reference, now has a playable tank. You dose ammonia, wait for filter bacteria to grow, and test ammonia, nitrite, nitrate, oxygen and temperature before stocking. You feed fish, change water, trim plants and arrange stones and wood, and time runs at real speed or up to a day per minute. A five-minute quick start covers the basics. A developer testing panel was still visible when we looked.
