Mine are not from petco, but they were babies/juvies when I got them and there is quite a big difference in their looks now that they are adults. I just had to share! I love seeing pics of the baby fishies and how they look all grown up! :3
This is Galileo. Look how tiny he was!! I don't have large fingers and look at him in comparison to my finger. He was only maybe an inch and a half at the most
This was Esmeralda when I got her. Poor thing she was so skinny! and her tiny little ventrals were so small. She was very tiny.
Now look at this big boy! He has grown soo much he is the size of my entire index finger now. A monster!!
And Esmeralda is a big girl now. She is 2.5 inches long now. A huuuuge change! Her feistyness has not dimmed in the least though.
