First off, here is a picture of my set-ups:
Betta [5 and half gallon]

Brackish [your standard PetCo 10 gallon tank, half-filled]

Here is a close-up of the rocks and gravel I am using for the brackish.

No idea what kind of gravel exactly, I'm told it looks expensive. It came with a 75gallon tank my dad bought from a friend a while back with stand, 4 pumps, rocks. It does have a certain odor to it when moist, almost smells like cement?
So what do you think of them?
These are my very first aquariums ever, so yes, I am a newbie.

Good news, I think. The little one has gone all the way from one corner of the tank to the opposite one, to hide underneath the rocks, in a dark place. When I shone a flashlight briefly it reacted, something that it didn't do up until now. I also stuck my finger close to her and sensed it, which made her move out of the way. Up until now she wouldn't flinch until I actually touched her.

I did a partial water change, I extracted 1 gallon out of the 4 and replaced it with freshwater in an effort to decrease salinity. It went from 1.007 to 1.005 and a half. It's a bit hard to read on my hydrometer but I didn't drop it more than a point and half at most.
I think we're on the right track, hopefully she will eat something tonight [it will be hard to tell] and even surface.

You guys have been most helpful. Not to bash Aquarium Advice [aquariumadvice.com] or anything but my questions have been for the most part ignored

So, she is a female red clawed crab. Once she pulls through this, can I get maybe one more? Can it be a female fiddler crab? If I do, how should I best handle the tranzition from freshwater to brackish?

Now, as far as keeping things clean and taking accurate measurements I would like to say in my defense that I've been building computers as a hobby for 11 years now and I work in IT. I'm pretty good at keeping everything tidy, up to date, organized and can guesstimate a CPU's core temp by touching the heatsink :P
