Besides the congo technically needing a larger thank (30G), everything else could work as a singleton in a 20G... so really just depends on if the OP wants to have a group of them or a singleton...

Ahh your right! Sorry about that! I was trying to think of puffers that would likely be on that list and would fit in the tank..the for some reason I put the Congo in with puffers that require 20 gallons...I was just doing to much with my brain at one time! Thanks for the correction
by dwarf puffer, are you including pea puffers? they are super small and I would think you could do more than 4 in a 20g tank. but correct me if i am wrong
