"Arowana Raising from Fry" is an iPhone game that allows players to raise Arowana fish from fry to adults. The game focuses on the care and growth of these fish, requiring players to provide fresh food for them to thrive. By feeding the Arowana, players can witness their bodies gradually changing color, adding a personalized touch to their growth.

Players have the responsibility to ensure the Arowana are fed regularly, as neglecting to do so will result in the fish dying. The game offers an easy operation where players can escape catches by simply tracing the screen. Additionally, players can earn points by cashing in excess food and use them to purchase backgrounds and other fish to create their unique aquarium space.
