They are about the same size as the powder oranges. So what are these gray ones? Too big to be dwarfs? Mature dwarf whites? I'm at a loss, and its driving me nuts. Are the small white ones the immature version of the large gray ones? Thanks for the help
Isopod identification from a fairly blurry picture is not going to be overly accurate.
My best guess is that the darker/larger Isopods are Porcellionides pruinosus "powder blue" and the smaller white ones are either their young, or the dwarf white Isopods. Could easily have been that they got cross contaminated (using the same tools makes a potential to contaminate cultures).
