Fish Tank - short introduction

About Fish Tank, from BoardGameGeek:

Fish Tank is a tableau-building game in which each of the players collect fish for their aquarium. Each kind of the fish has different criteria for scoring; some prefer the edges of the tank, some like to be in the middle, some like to gather together and some don't like to have their kind around them. The players draft their fishes in 2 phases of the game, each consisting of 8 rounds. At the end of the game, each player has a 4 x 4 tableau of multicoloured fish in front of them. The player whose fish tank generates the most points is then declared the winner.
