Your video is cool! I like the color of your betta. He is almost the same color as my Benji. BenjI is also blueish green but he looks more blue. Also, he has a little bit of red on him. It looks like your betta is very healthy and energetic. Nice tank too. BTW, what is his name?
My first thought and it was really a strong one is that I loved the way he browsed about the tank (beautiful tank, by the way) so he should be BROWSER. Of course that is just a suggestion. I enjoyed the video so much I put it on my bookmarks. He is a real beauty and so very graceful.
