eggs. she has a fungus on her shell. i fed fish guts recently and suspect that may be a cause. i was considering a salt dip, but don't know if that would be harmful for her. the salt i have is API aquarium salt. on a side note, would it be harmful to put in a bit of salt for the mollies?

OK I see now he's in a bottle and that may be your problem now unless you refresh the water in that bottle a few times a week it may be getting stale and not fit for the cray although you do water changes its not affecting the bottle,

take the bottle out and make a cave or put ½ a flower pot in or buy one where the water can flow through, you can do a light salt dip but don't add salt to the main tank and only dip for 1 minute
