This was sold to me as an amano shrimp. When I first got a closer look at it I thought it was a low grade neocaridina as it had a few patches of darker pigment, but now it is pretty much all darker cryptic colored. I noticed these vibrating things next to its face while it's eating that my other shrimp don't have - is this some other kind of caridina shrimp maybe? Or is it a parasite at work?
I don't think it has fan hands like that shrimp but it's hard to get a close look since it mostly hides - in some ways it's markings are similar though. I will try to update with more pictures when I get a good chance.
I'm also wondering if it could be a ninja shrimp.
