I really hope you did your research before jumping into this! People reccomend tha you do not breed veiltails because they are so common, most people want crowntails, deltas, etc. instead a VT.

Please, please go google betta breeding or even join a forum. I know Ashley and Erica who both breed bettas are members of TFF (http://www.fishforums.net/). I am a member myself and when I had questions about my betta they were always able to help.

Good luck.
