For liverbearers wild type swords might be a fun thing to try. Swordtails are not quite as prolific as guppies. They grow slower too.
To the first comment: yes, of course one or two fry is different than a tank full of fry. One betta would definitely not enough of the fry to make a difference before the babies got too big for them to eat. However, healthy bettas are absolutely fast enough to catch the fry, unless the fry can get to a place in the tank that is too small for the betta to follow.
Platys might be another good choice - lots of different colors and markings, and like swordtails, they are less prolific than guppies and grow slower than gupppies. However, less prolific is relative - they can still have 20 to 40 fry every 30 days or so, and the fry hide better, making it more likely that some will grow up in the tank with the adults if there are enough hiding places.
Also, platys and swordtails can crossbreed - just an FYI.
