Feed fish and fight aliens in the craziest aquarium around! Work fast to keep the friendly fish fed and happy. Collect the coins they drop to buy better food, new fish species and awesome weapons. And make sure to use those weapons on all the alien intruders, or you'll be sunk!Insaniquarium can be played either in Adventure, Time Trial, Challenge, or Virtual Tank mode. In Adventure, Challenge, and Time Trial modes, money is collected from various species of marine life in the player's tank. It is dropped by guppies, carnivores, guppycrunchers, beetlemunchers, and ultravores. Each lifeform must be kept alive by feeding it, whether through fish food or buying other species of fish. * Guppies: yellow with rose coloured fins. Must be fed fish food. Babies drop nothing, medium fish drop $15 coins, and adults drop $35 coins, ones which have constantly been fed (without being allowed to turn green) and have turned blue (and gain small crowns) to become king guppies, they will drop diamonds worth $200. This process is helped along by Blip. When guppies are hungry they turn green and purple. When guppies die, they turn upside down, turn white and make a sound before they fall to the floor and disappear. * Carnivore: black and red. Must be fed baby guppies. Periodically drops diamonds worth $200. Carnivores are larger than guppies and are the food for Ultravores. * StarFish: translucent yellow and pink. An adult guppy that has eaten a Star Potion (which costs $250). Drops stars worth $40 that can be eaten by Starcatchers. Star Potion kills baby and medium sized guppies. StarFish can grow into King guppies if fed long enough. If you feed it Star Potion while it's King it will stay the same as Star Potion only works on large guppies. * Starcatchers: gray, with tentacles and a bucket-shaped head. Must eat stars dropped by StarFish. Stays on the bottom of the tank. Releases a $200 diamond after eating a star. * Guppycrunchers: brown with pincers. Must be fed baby guppies. Releases beetles worth $150. * Beetlemuncher: bulbous-eyed and green. Must eat beetles released by guppycrunchers. Produces pearls worth $500. * Breeders: yellow with red fins and large stomachs. Must be fed fish food. Babies give birth to nothing, but medium and adult breeders give birth to baby guppies periodically. * Ultravores: large, bluish-silver fish. Must eat carnivores. Drops treasure chests worth $2000. Ultravores are large, about three times the size of a carnivore. When Ultravores die, they turn upside down and their eyes become pitch black and they emit a large gargling sound.
