This game is a huge disappointment compared to this developers Virtual Families game. Unless you really, really love fish, I wouldnt bother buying this game. Supplies (medicine, tank filter, etc.) are extremely expensive to buy, yet the average selling price of a fish is $4. Rare fish sell for a higher price, but are very difficult to come by. This is also an incredibly boring game - theres nothing to do but watch the fish swim aimlessly around the aquarium. And if you dont constantly play the game (which I didnt, because it was so boring), youll come back to find most of your fish (baby & adult alike) have died, and then you have to start all over again. If you want a good game from Last Day of Work, I recommend their Virtual Families game instead.
