Beans, if that's a betta it has the worst case of fin rot ever seen here on AA :p
I bought a male and female pair last week, will take pics tomorrow, as it is past their bedtime.
Edit: here are the pics.
Male plakat betta, which Petco sells as a 'king' betta. Whatever.
Female betta. These were not paired up by the store, but I wanted a female which is somewhat close to the male in color, and I found one. If the male would actually swim into the light for me, you'd see the black 'mask' and overall blue color like the female shows here. This female is less than half the size of the male; I think they sell those males as fully-grown adults, and the females are probably not.
