I have just been to my LFS and purchased the above named shrimp,Well i was certain they were dwarf crayfish,but was told they were shrimps and legal,They were a stunning red and i purchased 3,thinking i had got some new legal inport,But came home to check and found them to be Cambarellus patzcuarensis a illegal dwarf orange crayfish,So with all the info from pratical fishkeeping i returned them,to find that these had legaly been allowed into the country,After being checked off with all the import papers,which i was shown,The manager was shocked to see my paperwork,And said he would invetigate,How can these illegal crayfish get through like this,No wonder so many shops sell illegal stock....
