Calappidae
Harlequin Shrimp
I got this tiny ghost shrimp sized mantis at my lfs yesterday. I think its a wennerae but I can't tell. It is all red, white meral spots, clear red scales, and few very white spots around body, part of the claws are blueish green like the wennerae pictures on roy's list. LFS just called her a red mantis shrimp. They also had another that was small like her but it was black or greenish too small to tell so they are a color changing one. I found out it is a smasher from the lack of sleep I got last night from it hitting the sides of the container.. my peacock is more quiet. It eyeballs everything in the tank outside of her container so its more aggressive like a gonodacylus.
