thawed shrimp only and table sized on the big ones break it up if you think it is to big they are very nutritional for the Nem as they have a bit of iodine in them. Myisis shrimp are cold fresh water shrimp not salt water and do not have the same properties in them you can feed them to the Nem they are higher in protien value if they are the PC myisis shrimp. Cleaner shrimp will take stuff from Long tenetical Nems Mine do all the time.
