Am I overstocked in fish as of now?
In my 30 gal I have

2 female guppies (one is pregnant)
3 mollies (regular) 1 m / 2 f
3 platies 1 m / 2 f
2 male albino cories
3 guppy fry (assuming other guppy was pregnant.)
1 ghost shrimp

I'm fairly new to all of this, however my tank has been established for nearly 6 months. It's landscaped and decorated. Yes, my tank has been cycled and I monitor my nitrates, nitrite, ammonia, Dissolved O2, temp and Ph levels biweekly. :) However, I got all these new fishies as a recommendation from my LFS after my other fish died. (not all at once, progressively) . I'm wondering now ( about a month after LOL) if he sold me too many fish, or set me up for a tank overload with the the coed livebearers. Oh goodness.
 
A general guideline is about 1" of fish per gallon, but this really only applies to small fish. I think you can fit some more fish in there but if you try to keep all the fry you'll be overrun soon enough.
 
Cories are much happier with 5+ in their school. :> I think you're good, as long as you do plenty of water changes and have powerful filtration. You may want to consider getting a smaller tank for the guppy fry if you want to keep them. I'm pretty sure most LFS will buy them. ;)
Add some more cories!
