I do not recommend bamboo shrimp for several reasons:
1. As bamboo shrimp very rarely breed in captivity, it's safe to say that 99.9% are captured from the wild, putting strain on the wild population. It's possible to breed them, but it;s such a fussy process that few bother, which is sad. And they certainly won't breed in a betta tank or any other kind of regular aquarium set up, so each one sold as a tankmate is just hastening their extinction.
2. They are heavy filter feeders and require a higher flow of water than bettas generally prefer, in order to sift the water for food.
Most bamboo shrimp starve to death, because they aren't getting enough algae from the water column to feed on - they actually require 'green water' feedings. If they are scouring the bottom of the tank for food, they're starving.
Oh - and bamboo shrimp are more likely to get hassled by the fish. They can and do stand up for themselves, too, but I'm not sure what sort of damage they might do in that case. Mostly they are pretty peaceful.
I'd not mind attempting to breed some, one day.
