Problems with my fish

[bianca90]

I have a 3 month old 40g tank, I started with damsels and clowns, and I found out I over populated the tank. (my pet store didn't tell me). Since then I haven't bought anything else. Well, I have been missing fishes very often, just a week ago about 5 of them died. And today I'm down to my last one. I test my own water and also have my local pet store test it as well, but everything seems to be great. My fish had ick, which I treated and they seemed to get way better, they didn't have any white spots. I feed them every 2 days flakes and shrimp. I have no clue why they are dying! Any suggestions.?..
