From the back of the box:

What a funny fish tank! Little fish, jellyfish and huge sharks all want to get into the tanks, but it's not big enough to hold them all!

You need to think ahead and be very observant in this original version of the BATIK game, so as to get all your fish into the tank! As soon as a player's fish sticks out over the top o fthe tank, his opponent is the winner!

Contents: 18 wooden playing pieces (fish), 1 transparent vertical game board. Full rules of the game inside the box.
