Help! Missing Shrimp

I recently introduced a school of pseudomugil gertrudae to this 10 gal planted tank. This tank had a colony of maybe 50+ shrimp and after introducing the fish, i can barely see 5 shrimps a day. Are pseudomugil aggressive towards shrimp, cuz i searched everywhere and all it says is that they dont have big temper nor aggressiveness. Btw all tank parameters remained the same. What can i do?
