Fish Tycoon is a Nintendo DS simulation game built around raising, breeding, and selling aquarium fish. Inspired by the PC game, it combines real-time tank management with genetic crossbreeding and shop-style profit goals.

• Cleaned, tested, and guaranteed to play. Authentic cartridge.
• Touch Screen controls are used to care for fish in virtual tanks as they grow in real time.
• Crossbreeding species creates unique hybrids, with more than 750 possible fish combinations.
• The main puzzle centers on discovering the 7 Magic Fish through breeding experiments.
• Gameplay blends pet-care simulation, resource management, and entrepreneurial fish sales.

The DS version adapts the original PC-style tycoon formula to stylus-based aquarium management. Its breeding system gives the game a clear long-term objective beyond simply keeping fish alive.
