This is not really a game; It is a real time aquarium simulation. You get a beatifull animated aquarium with fishes that you buy, feed, breed and play with, like a real aquarium. Day after day, week after week, see your fishes grow, mate, age and fight. You can give them names because they may last several months, and give you children
