The bettas I've kept seem mostly fine with all sorts of snails. But shrimps seem to be out of the question - even if the shrimp is too big to be eaten (like yamato and 'feeder' glass shrimps), the betta usually keep disturbing and chasing them until they die, or jump out of the tank, unless you have a large tank with lots of hiding places where the shrimps can retreat to.
