Hey, Hermione, welcome to the HCA! Great job on being informed on on crabs before buying, and also for rescuing her!
You tank looks great, greenery always spruces everything up and the moss pit looks spectacular! One thing is just to make sure the entire ground is a constant 6 inches, from the pic (it might just be a trick of the angle) it looks a bit short of that, which is mostly a problem once you get her friend [which you should try to get soon!

] If you find you don't have enough space to hang the moss pit, you could always let it rest on the ground of the 'tat. Only other thing is to make sure Hermione can fully submerge in both of the water dishes, and possibly a bigger amount of shells, it's hard to see all of them, though, so maybe I am mistaken.
Oh, and I almost forgot, I'd recommend moving the humidity/temp gauges closer to the substrate where she will be for an accurate reading.
Great job on the crabitat, I think it looks very nice!
