I am far from a pygmy expert, but have had a few. I would think if you had something like a 55 gal or larger aquarium that you could house 2 males. But you would need to be sure there was lots of cover so the didn't really see each other. jmo
Thank you Laurie.
I plan on making it very well planted with tons of driftwood, branches, etc. I am still not sure on what size the ending result tank will be. More than likely it will be a home built one. I should have plenty of time to get it done. They will be hanging out in 2's in 10 gals till I make sure every one is eating and doing well
