Hi everyone! I'm new here, and my name's Amanda. Here's my story: I'm a college student, and a week ago today I bought a (very illegal, I now realize) baby RES in Chinatown. He is tiny tiny tiny - his carapace is maybe three inches long, tops. It was not the most well-thought out purpose, in retrospect, but I love my turtle and I'm determined to do the best I can for him. The day after I bought him I went to the local pet store in town and got him a 10 gallon tank, some gravel, Reptomin, Reptotreat (the dried shrimp), and some rocks. I cleaned the rocks and set up his tank, where he now has a multi-level basking area. However, once I started to look up turtle care online, I realized that most people's turtle setups are much more extensive (i.e. heater, filter, UVA, UVB and basking lights) than mine are, so I went back to the pet store and told the manager my problem. He told me that a lot of people get these as pets and that when they're really small, like mine is, the setup I have now is fine; he said that I don't need a heater or a filter or anything like that yet, just to change the water once a week and come back if he seems to be growing, because then I will need a new tank. (He also told me that my turtle might not get any bigger; he said that most do, but a lot of times the Chinatown varieties don't). I've followed his advice, although I change the water and clean the tank every other day - warm water, a toothbrush, and a little bit of Dr. Bronner's for the dirt on the rocks - because the water gets really dirty, and I read on a website that you should change the water every few days if you don't have a filter, especially if they're babies. I feed my turtle a couple of Reptomin every morning and then usually a couple more in the evening, although I sometimes give him the dried shrimp instead and last night gave him a little bit of raw hamburger, which he loved.
I realize that his setup is not the most conventional, and I do feel a little guilty about not being able to have a really big tank, filter, and such. However, this really isn't possible at the moment. I'm in college and money's tight, not to mention the fact that pets, uh, are not allowed in my house so any big setup which calls a lot of attention to itself is a big fat no-no. I do have a desk lamp with multiple adjustable lights, a couple of which I've angled at the tank near his basking rock, which he seems to like. The tank is also on my desk near a window, so he gets a lot of natural sunlight, and I gave him a vitamin D yesterday.
As small as this setup is, though, he seems to be thriving. Aside from a little bit of peeling skin around his tail, he's very healthy. I read that a good indicator of your turtle's overall well-being is if he flails his limbs when you pick him up, and he certainly does, at least until he feels secure with my hand under him. He likes to root in the gravel, bask on the rocks, and cruise around his little body of water. He'll stay still in my hand for a little while, and then tries to zoom off, but he never bites. His appetite is good, and he loves to swim in the tub when I clean out the tank. He also likes to come downstairs with us and watch movies in the evening; I am not making this up. He has definite preferences - He's a big Alan Rickman fan, Kevin Smith holds his attention, but Cirque do Solelil, not so much. 
I guess what it really boils down to is this: should I keep worrying about his setup, or keep it relatively as-is so long as he's healthy and this size? I've been concerned about this, and I'd love to hear some thoughts, especially about feeding, because, as someone said before, I can't get a straight answer on that subject and I'd like to know if I'm feeding him properly. Sorry this was so long, but if you've read this far, thanks, and I hope to hear from you!

P.S. I just realized that I never told you his name, which is, in full, Crumpet, the Metatron, Lord of the Hot Sex Breeches (I live with a lot of crackpots who all had a hand in the naming). We call him Crumpet or sometimes the Metatron, but he doesn't really seem to mind.
