I would agree with Trenac, but also that the shrimp we call "Ghost shrimp" is a pretty ill-defined group. They sometimes include the male Cherry shrimp who aren't as red, long-arm shrimp that can end up attacking and eating fish, and basically any clear-ish shrimp they find. So, there very well could be some algae eaters in some of the Ghost shrimp populations out there. Hopefully, we'll have better descriptions as shrimp become more popular in the hobby.
