I agree with the previous posts that each betta has its own personality, so there are no guarantees. However, I have successfully kept male bettas with platies, tetras, otos, and adult amano shrimp.
One approach that I have found useful is to ensure that the betta is the last fish added to your tank. This helps minimize territoriality. If you don't have the betta yet, add all of the other fish to the tank first, then introduce the betta to the tank last. Ensure that you monitor the tank to see how the interactions go.
If you already have the betta in the tank, remove the betta, rearrange the tank decor as much as you can, add the other fish, and then add the betta back in.
