OERBT are royalty in the shrimp game. The tiger stripes on these guys are barely visible without direct light and they have a deep navy blue coloration all the way through. The orange eyes stand out and can easily be spotted from nearly anywhere in the tank. Some research has stated that they are blind but in my experience, they seem to find food just as well as my other shrimp, however, they seem much more active when the lights are dimmed.
