So long as the shrimp is not given more than 3 meals a week it is okay to give it to them but after fry stage it is considered too rich for them full time. It puts too much weight on them and not enough good healthy nutrition for them. The best food for them is still usually their favorite...bloodworms. Just be careful as the main problem with bettas of all kinds is that they have no appetite control. They will literally eat themselves sick. I hand feed all my bettas that I own and make them control themselves by limiting what they are given and make sure they eat every mouthful before offering another one.
