Not the one in your picture. :)
Consider freshwater community (not agressive or semi-aggressive) species that don't get too large such as zebra danios, mollies, sword tails, cory cats and various tetras. Betta can do well in a community setup too, as long as you introduce them after the tanks is established, don't include other fish that look similar to them (such as some mollies), and don't have any "fin nippers" in the tank (such as barbs). However, every Betta seems to have a different temperment, so its always good to have a backup plan if he doesn't play well with the others.
