You know I just saw my first baby fish a few weeks ago. We bought Sofie 2 goldfish and one ofthem we thought was going to die cuz it kept sitting on the bottom of the tank. Well, tuned out she had a baby. It was so small, you could barely see it, but an itty bitty fish all the same. One day it just disappeared, so either the other one ate it, or it got sucked into the filter, I have no idea. I wish it would have made it though. The girls thought it was so neat.
