Shrimp ?..........? blue
I have this strange and dark blue shrimp in an EHR. You see, almost black. Shrimp do not know this existed. Can someone tell me, what are their names? The shop called Black Bee, but do not think they are. I also bought an orange shrimp. They also requested that the shrimp orange bee shrimp. Both are about the size of a regular ghost shrimp. Both cost $ 4.50 each. I want the kind of shrimp, which yes, I got to know a lot of them? I bought one of each.
