my cherry shrimp are looking weird. their backs have this weird dull spot. its not the saddle its like a stripe down their back that is dull. im not sure what this means. could it be their molting? what should i do.
usually the cherrys do not have this strip down their backs... only PFS have them, but if you have one on your cherry that just means they have the genetics of a PFS at one point in its time it was inter breeded with a PFS
