Fat legs??? Water maybe???

Hi all! I have a very bizzare question … the CrabPot Clan are giving me the runaround … minor issues, all taken care of for the most part. But I noticed something with them that wasn’t there before. Their hind legs seem to have pockets of fluid … It’s not fat … too squishy. It’s between the leg and the shell in front of the leg. They all have them, but did not before. The pockets feel like they are full of water. Do I have a problem?? They eat enough. Kinda looks saggy when you lift them up out of the water. Also, just as a follow up, the skin fugus is caused by poor water quality? I want to make sure to KEEP IT AWAY!! Thanks all!
