Welcome to the forum!! He is really cute!! As far as names go, I would really consider his name carefully and watch his personality. I have a few bettas whose names don't fit that well because I was excited and jumped the gun. As far as advice goes, the things I gan see is that he might appreciate a heater and some hiding places. You can go get a pack of 3 of 4 chap plants at petco or petsmart for under two dollars, but silk or live plants are the best. Bettas live in "75-85 degree water," but it seems to me like most of us here prefer about 80-82. Personally, I am an 80 person. You get what you pay for with heaters, but I love this one I just bought cheap for all of my tanks http://www.petmountain.com/product/a...le-heater.html
. It is a pretty reputable brand, and its a little better than your typical mass-produced pet store brand. If you can't afford or just haven't decided on a decoration yet, terra-cotta pots work great and a lot of us use them!
If you have any questions about how to use or find things on the forum, or about keeping your fish in general, feel free to ask!! :D
