In the US, I went to a Petsmart and a Petco, and in both I found that the bettas were a lot smaller than the ones I've seen at home (Montreal, Canada). The ones I've seen in stores around me I assumed were adult sized, about 2-3 inches in the body. Most of the ones I saw in the US were only about half that. They didn't look like the pictures of babies that I've seen on here, they were fully coloured and had decent sized fins - pretty much adults in miniature. Are they just a little bit younger? And if so, does anyone know why there's this weird difference between stores there and here?
