Depends on the individual fish I think. I put off buying them because I read so many posts and articles that said they could be difficult to feed. I set up the tank with a good amount of RCS and ordered the badis. The tank is on my desk so I watch them a lot and as far as I can tell they don't eat shrimp. I've seen them next to shrimp fry and not touch them, and these are wild caught fish, not captive bred. They do love frozen blood worms though. On the other hand I've watched my clown killies stalk shrimp larger than they are!
