I would like to know the smallest aquarium fish I can purchase. I have read all over the Internet but I want to see what my fellow planted tank members have to say

Least livebearer, or heterandria formosa.
Danionella translucida or danionella dracula, not sure if they're the same fish but they're both a little over a centimeter.
Thanks guys for all the input
