What kind of filtration system are you using? All semi-aquatic crustaceans like crabs produce ammonia as a primary waste by-product that when not properly filtered can (and will) become toxic to the crabs. When left unfiltered, this ammonia build-up leads to higher levels of nitrites and nitrates in the environment which are also toxic to the crabs. Unless your setup is properly equipped with a filtration system, this will kill your crabs. Trust me, I have learned the hard way (i.e., I have also lost many red claw crabs through this "learning process)." As you probably realize, being part of a forum such as this is very helpful to both novices and the pros.
The only reason I ask about your filtration system is because I hadn't noticed you mentioning anything about it, and before I invested in one myself I lost many crabs, and also like you, was doggedly determined to get it right, by hook or by crook.
Also consider how much food you are providing your crabs. It seems like you are sort of overdoing it. You must realize that any food that is left in the tank uneaten must be discarded (either scooped from substrate or siphoned from the water) within a 24 hour period because if it is not it will also contribute to high levels of ammonia in your tank setup, which again, is toxic to the crabs. These crabs are extremely sensitive to their immediate environment and any minor shift can cause undue stress to your little friends.
Fiddler crabs are a bit hardier and can withstand elevated ammounts of these chemicals a bit more easily and are generlly less sensitive to these types of conditions, but I am sure that someone in the forum will take issue with me making that claim. I am just speaking from my own personal experience.
