Tank 1 is the first tank in Insaniquarium. It is the most basic of all tanks in the game, having the cheapest egg prices, the cheapest laser costs, and the smallest food chain. The guppy and carnivore are both introduced for the first time here.
Tank 1 takes on the appearance of an average and basic fish tank. Its color palette is mostly made of blues and beiges. There are several leafy plants spread out in the tank, and there is a rock to the left with coral growing off of it.
