Saw the image and C. japonica there're NOT.  I've a couple of these in
my tank and mostly hang out at the outlet tube, filtering particles with
their highly modified pincers... actually they look like spread out dish

Yup they are the Wood/Singapore Shrimp and are usually orangey after
molting but soon after, the woody grain look returns.

Not much info is available for this species but mine doesn't eat algae
and are happiest near the water flow.  From my observation, they don't
swim very well but they don't harass small tetras either.

These are very interesting characters in the tank and have a unique
eating behavior.  Personally, I'd keep them.  Besides when were LFS 100%
correct ;-)
