Baby bettas

[masterdan407]

My room mate's girlfriend bought two baby Bettas from Petco the other day. I have everything to take care of them including: multiple types of food, heaters, etc. I was just wondering if anyone could give me some info about them. Like if they are old enough to tell tail type or gender. They "look" healthy, but they probably weren't taken care of in that little container in Petco. Anyways, here they are!

Bottom is most likely female and perhaps delta tail? The top looks to be male and veiltail or delta. :)
