I think it might be a mix between different colors of cherry shrimp, but could be a more "natural" wild type as well. I have some that looks quite similar in my tank (including with the pale stripe) - and I swear I never bought that particular color, so it must have happened when the light was off...💞 Anyway, I love them just as much as the brightly colored onesLooks like a brown/wild type neocaridina
