What do you plan on doing with the 36 guppies, they won't fit in your 29g tank even if it were empty. How do you plan on keeping them all? Also don't plan on giving them away, since that probably won't always work. Also, don't keep all of those minnows as they will make your tank harder for your other fish, and they will make your tank way overstocked. Plus they prefer colder temperatures which makes it harder for other fish.
