"There was once a hidden and mysterious island called ISOLA. Hidden in this island was a magical lagoon where the most rare and wonderful fish swam. These fish lived in a delicate balance held together by 7 special magical fish....Once day something happened...Where have all the fish gone? You must find the 7 Magic Fish and restore the balance. You must save Isola!....."


The object of this tycoon game is to discover the 7 MAGIC FISH of ISOLA and restore the island to its former glory. You start with a small selection of fish, some money and a tank. You must breed them, care for them, help them grow, and cure them if they get sick. Along the way you can buy supplies, medicine, research technologies or invest in advertisement to enable you to discover rarer and rarer species until you find the Magic Fish. All of this will be financed by selling exotic hybrids in your shop.

The game runs in TRUE REAL-TIME, so that if your device is turned off or you exit the game, hours later small fish will have grown larger and new surprises await you.
