My Betta Fry I found last week at Petco.
http://www.youtube.com/watch?v=jECbNPZA1O8I found this baby Betta last Thursday at the local Petco while in search of a new male for my divided tank. I got her along with a White Male Super Delta tail. I picked her up because she's about 4-6 weeks old and obviously not able to eat adult Betta food on her own. Due to this and her being only a fry, I knew that I could give her the extra care she needs to survive.
This is her in her 2.5 gallon tank, exploring and eating bits of flakes that where crumpled into crumbs. I'm currently awaiting the new batch of BBS to hatch. The stuff you see floating around are bits of her food and air bubbles from the filter. Also, you can't see it in this vid but the ray branching on her back fin suggests that she's a crown-tail. She also may be a he. It'll become more apparent in a few weeks.
