It's seem like everything I get from the grocery stuff has a bit of sodium no matter what even if it's organic. I'm in University, so I don't always have the greatest food / treats for them. I bought organic honey & organic frozen shrimp but they still have sodium, even organic carrots I bought have a bit of sodium in them also. Is a little sodium for the little crabs bad? If so I really have no food to offer them. PS: Would defrosting frozen veggies be bad for them also? Since it contains sodium.
