It's definitely not a
Palaemonetes ghost shrimp -- the body form is clearly atyid. I'd say it's some non-Amano species of
Caridina. The rostrum and cephalothorax don't seem to indicate
C. thambipillai -- this is the actual name of orange/"sunkist"
C. cf.
propinqua -- to me. The resemblance in coloration is probably just superficial -- it seems like its dietary or otherwise environmentally induced even in
C. thambipillai (
captive-bred F2s are more transparent).
The muscle tissue looked a little hazy in your first pic. If it gets to be opaque, the shrimp is almost surely on the way out.
