Bettas do jump, some better than others.
Some of my bettas have learned some 'tricks' to perform on cue. Shrimp will flare on command when you show him a yellow cap (like the ones I have for my water jugs) and strut about in a circle, then shoot up to the top of the tank ... he knows he gets fed if he does it, the little monster, but he is so pretty when he does.
Mr. Rufflebut jumps for food, will snatch it off the tip of my finger, but I think that's just because he's a pig.
The blue and red delta in quarantine (the one in my signature) is also turning into quite the jumper. I put the food bottle on top of the lid on his tank one day while I went to mess with something else, and the next thing I hear there's this thumping sound. He was jumping so high trying to get the food bottle (not sure if it was because he could see the pellets in it, or just because it was something up there) he was hitting his lid. Which, from the surface of the water the the lid is two inches! Now that he's recovering (I should update my sig) he's become much more active, and I have hope of being able to teach him some things, he's pretty quick.
Crichoid and Xyphoid will both do the wiggle dance and follow your finger around the tank any time you put it up against the glass. Although how difficult that really was to teach is questionable, they already did a wiggle dance every time I went to go feed them, so I think they just equate my presence with food.
