Okay, I agree he needs more hiding places. And even if that gravel isn't as bright as it looks, be assured it's bright to a betta. Floating plants would be excellent (even fake) as well as the log already suggested. He's stressed out. Here is a pic of my 55 gal. tank. I know it's a lot bigger than yours, but my betta sorority (among the other fish in there) love to hide and play in the plants.
