HB Blue x Japanese Blue x Red Mosaic x Black Bar Guppy Endler (Hybrid) Pair

It all started one day, I got a pack of Half Black Blues and Japanese Blues from a reputable breeder. I only orders Half Blacks and I thought they were just stressed so everyone went in the same tank. Later I realized a hybrid came out of this and they seemed quite a bit more robust than the either parents strain. 

Eventually I spread that population out after a few generations to a black bar endler population and and another group to a red mosaic guppy tank. Another switch and the descendants of those tanks mated and this is the result, 3 generations later and we a closing in on the genes settling. There are still some anomalies in the gene pull but that's the fun of it. They're hardy like black bars although admittedly black bars seem to withstand it all.
