New Endlers

I've recently bought a few Yellow Jacket Endlers from another guppy hobbist and I've began to breed them. They are guppy-endler hybrids and my first 'endlers' that I've ever worked with. I hope to get alot out of them and they seem to be very nice stock. They are similiar to Tiger endlers but are a bit different.
Heres some pictures:



They are beautiful on their own but I also wish to cross them with some half blacks I have. I am hoping the cross turns out as nice as this cross:
