pb - which panda's do you have?
I imagine they're mostly xiphophorus maculatus with perhaps a bit of variatus mixed in - your standard domestic platy mishmash. I bought them directly from Imperial Tropicals last year. I received 1 female and 5 males; of those, the one female survived. She was pretty small when I got her and she's grown a lot since then. She's been spewing fry continuously since I received her, many of which have survived. I think I have around 15 sexually mature (VIRGIN!) female juveniles at this point and just 2 males.
It's possible there's some hilleri in the mix too, but not nearly as much as with my sunburst platies - they're decidedly different in shape from my pandas.
I love the black coloration and so far they've bred more or less true - no colors other than black, white/pink, and every mixture thereof.
