Peppermint or Camelback shrimp?

[Chameleon]

Hey yall
Fist sorry for the double thread (i posted in invert forum too) but I need a quick response so I figured posting here would get better traffic.

I just got these shrimp that are acclimating now. I just want to make sure they are peppermint or Lysmata wurdemanni before adding to the tank. Please let me know. If I need better pics let me know too.

Hard to tell from the top down pics. Camel backs have a rather large hump where the tail meets the body. That's why they are called camel back.

I think they are peppermint...although i dont think it matters now...
I did something really dumb and instead of grabbing the acclimation specimen box I think I grabbed the dip one. shrimpy's aren't looking so good. really wish I had labeled the boxes properly. I always set one on one side of the shelf and the other on the other. maybe I mixed them up, but anyway I think residual bayer on the container is hitting them hard...sad day
I would jsut throw them in the tank to get them out of the bad water but not sure if that will cause more issues...thoughts??
