Onenobee, lookin' good man.
"Beautiful shrimps, but they will interbreed and their colors will be more complicated "
That would be true if they were from different strains. These are Blue Diamonds. They throw chocolates, blues, blacks and some other variations- all without reverting to total wilds.
When the first in line breeders (me included) received them imported from overseas, a lot of stock died off. Just too sensitive. Some people lost entire colonies within 2 weeks. Heck, I lost 2/3 of my stock as well.
My goal was to work with them quite intensively to increase their health and hardiness. I succeeded (to a degree,) so others could take over and have success with them and spread around the genes.
I have to say though, even though they are MUCH more hardy now (through blood, sweat and tears), I still consider them the MOST sensitive cherry variety around.
Onenobee was one of the fine people who bought out my stock and is continuing in that goal of making them hardy for hobbyists!
