Very intresting
Crosses are generaly very weak and rarly thrive.
Your's surly look like crosses and interesting.
Could you explain what you did and did you use virgin fish?
Hi. Thanks.
Well... a little history first: I've been breeding HB Red guppies for a few years and have also bred a line of Yellow Grass guppies and others. I love guppies, but I've always kept a mating pair of silver sailfin mollies just because they look nice and make nice community fish... plus the LFS takes mollies for store credit.
I've always been intrigued by hybrid species and so my first endeavor was a line of endler/guppy crosses which, sadly after years of breeding, amounted to mostly washed-out, semi-metallic hybrids which did not breed true. You can actually see a few of the nicer specimens in my videos. Meanwhile, The silver mollies mated and I experimented with a few female molly fry from each drop. Over the course of two years, I had two successful pregnancies between virgin mollies and a select male guppy, but in each case the female molly developed health problems and died many weeks later... In each case, suffering something symptomatic of hemorrhagic septicemia.
Discouraged, I changed tactics. I chose a sexually mature sailfin molly and placed him in a female guppy holding tank. The females at that time were just under 4 months old ...and yes... I've always separated males and females as early as possible,(usually within 2 weeks of birth)... especially so with this line of yellow grass guppy, as line-breeding between brother/sister produced bad results in previous generations.
I really didn't expect any of the females to become pregnant. In fact, I worried the molly would harass the females to death...literally, but I left him there for a week and then moved him back to the main tank. I never actually checked on the females again(aside from feedings and a water change). About a month later, I began setting up to transport the Yellow Grass guppies to the LFS when I noticed the fry! In all, 16 babies were saved.
My only regret is knowing many more fry likely became fish food... but anyway, they are very happy and thriving today. Since these videos, they have become much more colorful and their fins have really grown out.
I will have another youtube update soon.
