Yes KOD you are right, i should have made it clear, thats just in my own personal opinion, Guppies, Endlers.... same thing!!! Just my opinion, not a fact. I do keep both and yes i certainly prefer Endlers.
Edit: with the exception of the montrosities (guppies) that get bred out in Asia, the ones that seem specifically made to kark it within 3-months and spread disease within your tank!!!!
