I have so many experimental guppy crosses that I swear I find something new every day in my fish room. If I’m not paying close attention to a tank for a week or so, a younger or growing fish can make some amazing transformations in a short amount of time.
Compare the new male guppy above, to the one I posted yesterday (below).
I’m not 100% sure they’re siblings, but they do have similarities. The same double black spots behind the gills. A blue area near the caudal on the peduncle. A red spot on their bodies behind the dorsal. And gold vertical bars. The top guppy has more blue in his dorsal and caudal, and less overall platinum gold. But still a striking fish. The upper fish is also in better shape as far as the fin development, though I wouldn’t mind seeing a longer dorsal and maybe a thinner sword. And since there is no upper sword remnant to deal with, he would make a better fish for crossing.

UPDATE SEPTEMBER 2013. Alan Bias emailed some input on these to me, including his own photos. Click here for Alan’s website.
Alan says: They are very pretty, but hard to progress… First two photos are initial expressions in green and Pb….
It is basically Z-Bar with partial expression. Regulation in peduncle is often separate in upper and lower peduncle.
This is what I eventually evolved (below) them into with removal of red and a lot of culling. This phenotype was initially often linked to very late coloring “mules”. Only time I’ve ever had in swords. Yellow epistatic to red.
