Yeah, you'll wanna get him nice resting areas. Plants are great for it. I bought some water hyacinth and frogbit. The frog bit on little guys side sorta clumped underneath the surface on one part and he likes to go into the tangled roots/leave and shill there sometimes. Also, consider buying a resting leaf http://www.amazon.com/Zoo-Med-Betta-.../dp/B0027IZ6KW
Little guy doesn't use it all the time, but Starburst (the other male I have) likes to use it once in awhile. They also have a coconut? floating ring for them. I found both at my petsmart, though the ring was a bit too expensive for me at the time.
