My craws have a dark brown algae-looking substance on them - mostly on the bottom half of their bodies...meaning below what would be a lateral line if it were a fish. Actually only about half of them have this somewhat fuzzy thin film. I find that to be normal for older, larger craws. I think the cleaner looking ones have molted it off with their new exo. I'm not sure what's up with the rest of the situation.
