My nems still are in the same spot, but they are getting light and have eaten. They are starting to fill with water again, still not complete size, but getting there. I am just leaving them alone. The color still looks good, thankgoodness! One looked pretty bad saterday night, it was small and the mouth a little swollen, however now it looks fine, guess I just dont see them when they are deflated. When do u think we need to flip the rock back over?? Should I wait till they start moving?? Our tank is a total mess! I just dont know where to go now. Any advice would be greatly appriciated.
