I do the same thing. I have to fight from buying a betta when going to Petco. I love looking for baby bettas there. I actually plan on getting one more female and my first male. However, I am going to be honest when looking at the males so far I am not finding one that I like. I am picky when it comes to the males as the Petco has many males that are looking very sick. I am a mother of 3 CTs and 3 VTs but that doesn't make me a bad betta mom because I am only picking CTs and VTs. I think if someone is a bad betta mom would be if she doesn't take care of her bettas or doesn't ask questions about them.
