They were sold as "blue shrimp." This LFS has blue shrimp, green shrimp, and cherry shrimp, so I was thinking that it's a variant of neocardinia heteropoda (NH) when I was buying these. I'm not so sure now, they seem to be too blue to be NH. They have no stripes, and one of them have that band from the head to tail. I'm hoping that they are of high order breeding shrimp because the colors are so cool! What are these?
