When your hermit crab turns darker, does it mean they're healthier or weaker??

Question

My hermit crabs used to look a little pale but now, they're q REALLY deep purplish brownish color. Should I be worried or relieved??

Answer 1

it is just darker because you are feeding them stuff that makes them change color. deep reds and purples are really good sign good job! :)

and yeah i think they can pee on you because they drink water so they have to pee lol.
