Ok, I've finally decided to get a group of Balzani for a 65 gallon tank but have a slight problem. I was originally going to order them from my source and get 2 larger males and 4 smaller females. Unfortunatly my source has sold out of the larger males which i really wanted so now I have to go with 1 larger male at 4.5 and a smaller male at 3 inches. The females are all 2.5 inches. Should I just get the 1 larger male and 5 females or go with my original plan. The reason I wanted 2 males is because I'm afraid something will go wrong either during shipping or afterwards. Also my LFS has balzani that are much smaller and the store owner doesn't know where they came from and doesn't seem to even know the difference in the species from Uargary or Argentina. The Balzani at my LFS are small and I don't see any yellow indicating they are the yellow breed. Just wondering if most of the Balzani out there these days just come from 1 location?
