FINALLY! I've got Squirtle into her new home... or is it him? Now that I'm getting a better look, I'm not sure whether his nails are long or super long (like a males is).
Also, I've noticed that he's got this filmy thing on his skin (ie not on his shell). It almost looks like algae except it's greyish/whiteish. Could he have some sort of fungus? What is it? (some pictures below)
EDIT: After reading up on the main page about physical conditions, it looks to me like either skin shedding or a fungus. But they sound similar and I'm not sure if it's excessive shedding or a fungus. He's been living in horrible conditions with little water (and the water that was in there was INCREDIBLY dirty, I couldn't believe it), cold temperatures and no basking spot, so I wouldn't be surprised if it's a fungus. However it's all over her body (ie neck, arms, legs, skin parts), and not in just one spot, so it could be shedding.
It looks a bit like this:

When I was cleaning out his old tank, I found lots of plasticy slabs which, I assume, is from his shell due to shedding. After inspecting him I found hard flaky bits on his plastron. Is this normal?
If anyone could look at these pics and tell me, just generally (because I know you can't tell everything from just a picture!), how his health is doing? There are no "turtle doctors" here that know anything about turtles. My best bet is you guys. Thanks!

Shell and habitat:


Nails:

Filmy thing (in the second image you can see it around his neck). I tried to get a good shot of it but these don't really... "do it justice" it looks a lot thicker and filmier irl:
