About three months ago, I went for a short visit to the Monterrey mall for about an hour. When I returned, There were little half-inch baby fish swimming in my aquarium. Now, three months later, these "Baby Fish" don't really look like babies at all. They all are now almost 1 inch long! I should be able to start selling them when they turn 5 months. But don't they all grow up so fast?:)
