i got 5 peppermint shrimp the other day and i noticed that there is what looks like a complete shrimp skeleton or body. ill try and get a pic of it but just a description is that it is clear colored and you can see thru it easily. it is a complete piece antenae and all. all the shrimp are hiding under the rocks, i do see them but cant see em all at once to count them any ideas? molt or dead.
