If your water chemistry is OK, I shouldn't get too worried. Stringy poo's are fairly common as are periods of not eating. In fact our Long John Slither has gone to ground under the shells in his tank and won't come out for anything.........not even nice juicy crabs. Cap'n Black Beak is off his food too. Just leave some live food in the tank and he may sort it out for himself. If it's parasites there's little you can do.
The white spots do look like scar tissue so he may have received a nip but he'll get over it!
As for crab size..........that one in the vid is fine! Octopus (and squid) can deal with surprisingly large prey! I've seen one of our midgets (15 cm total length) tank on (and beat!) a crab of 15 cm carapace width!
