Thanks for the compliments. I'm not returning to pure strains, or to live bearing fish at all.
I've turned to concentrating on maintaining a planted community tank since I haven't space for multiple tanks and culling excess and undesirable Endler's is too much of a pain in the butt when you're breeding them in a 9 gallon planted tank. Plus I couldn't place all the excess Endler's and Guppies and had to destroy a bunch of them, which I didn't like.
