Looks like a black Betta - is it black or does it only look like it on the picture? if it's black - I think it's very COOL! Nice tank as well LOL ... there is either a small toy man or a sticker in the bottom left corner of the tank. It looks like it's a real tiny person staring at a giant Betta, hehe
you don't like pink I was thinking about that but since he is so pale I'm worried anything remotly dark will wash his colors out. and a planted tank background would look silly behind such a plain tank... decisions decisions.
