UPDATE!!: tested my water today only to find that my nitrites and ammonia were 0 and that nitrates were 7%ppm! yay cycle! So i went to my LFS today, and picked up 5 fish. 1 amber barb, 2 cardinal tetras ( they're so small!) and 2 platys.
Only thing is, I've heard cardinals (tetras in general) do better in schools of 6 or more.
