Betta breeding shouldn't be taken lightly, so I suggest you head over to the breeding section and do a little research to be sure you're ready for this.
Yup, I totally agree with nochoramet on this one. I found google VERY helpful when doing my research ;) And if your someone like me who sometimes needs to be able to physically see how something works, YouTube is awesome too. :)
