What do I do about these fish?

I'm in high school, and i spend my lunches with a few of my friends in this great classroom. The assistant has her won desk, and would keep getting, and killing, bettas. She finally stopped, and that made me feel a lot better. But after our spring break, I came in to see a 20 gallon tank, severely overcrowded with very ill fish. There are 5 comet (feeder) goldfish, all with fin rot and one that has gone blind from cataracts. One has part of his dorsal fin eaten off, and two others are lacking theirs entirely. There's another that's missing a pectoral fin. And one poor one is missing all but his tail and pectorals. There are TWO plecos, a corydora, ADFs, and three tetras. There's a filter, but it's certainly not strong enough. The water is disgusting, and she never does changes. She simply buys new (ill-fitting) filters. According to her, they're all two and a half years old. If so, each is severely stunted. And she just bought a bunch of new ones yesterday! I don't know what to do. I'm fine with pitching in and trying to nurse them back to health, but i know that she would need at least 200 gallons to safely keep them all. I have my own overcrowded tank at home, but it's not as bad and I change the water weekly. I wouldn't know where to start. Please don't respond with answers about calling the humane society or getting rid of them. I'm only sixteen. I just need to know what steps I can take to help the tank become healthier.

Do you think the dealer touched up the paint?

Just bought a new 2011 Kia. I've had it a week and today, while washing, noticed 4-5 tiny "chips" on the lower side paneling.. Below driver's side car door.. I first thought it was tar, and scratched with my fingernail.. that caused a bit more paint to come off.. It appears the dealer may have touched up these small areas before selling. Any thoughts?

Black Tar Glue contains asbestos?

I have linoleum tiles in the basement of my 1951 built home. The glue used underneath is black tar. I am aware that tiles from this time often contain asbestos but does the black tar glue also contain it?

REALLY NEED ADVICE ON THIS!!!!! (ARMPIT PROBLEM)?

I'm a 17 year old male, who is constantly sitting or lying down at the computer. I hardly do any physical activity. But for the past 2 weeks, I've noticed a very mild (sometimes sharp) pain in my armpit area (around the pectoral muscle area) that comes and goes. I mostly experience this pain at night, during the day I hardly feel anything. There is no swelling or other symptoms, just this pain. What could it be? (If it helps, I've had this persistent cough, which I got after a flu, and it gets worse when exposed or inhaling cigarette smoke, if any of this may be related). I went to the doctor, and he checked both my armpits, and said I may be allergic to the deoderants I'm using, and gave me a cream to use, which has not worked or relieved the pain in any way. I'm also not obese or overweight if that helps.
