I have always been bothered by brooding octopuses' lack of food intake and hydration. The difference in the female when she broods and when the eggs hatch show the toll not eating takes but how does she get fresh water? This line of pondering has made me reconsider procedures for thawing frozen foods. Freezing (especially in frost free freezers) removes most of the fresh water and I have recently changed to using fresh RO/DI water vs using new saltwater for thawing. The two octopuses I am currently keeping take the FW thawed at least as well as the SW thawed and I have seen no negative but possible (antecdotal and possibly unrelated) postitive response with skin color and levels of activity. Any input on how cephs obtain freshwater if it is other than through their food? Any ideas on how to determine if a ceph is dehydrated?
