Hey Aaron..
My wife has a 10 gallon guppy tank, lots of plants

and I lied about it being my wife's

She likes to look at it and pick out the guppies , I get to maintain it.
I am upgrading the tank to a 20 long. My experience has been an "exponential" accumulation of fry. Since I am 50 miles from my favorite lfs, I cull the school by potential color combination then net and release the fry into my large community tank.
It just occured to me that I could on occasion export a "bag o guppies" to folks who want them.
