This :
"This is normal with all new shrimp coming into the market, none breed true. Bloody Mary are supposed to be characterized as having short rostroms, yet a lot being exported to the us, and even bred and sold in the us have long rostroms. "

Is not true, this was a marketing tactic that one of the first creators of the stain said, that it had a short rostrom. They later balked at it when they were found sending out shrimp with out the short rostrom. a short rostrom would show as a defect in a shrimp more or less. The Distributor has now backed off this comment from everything I have read.

Bump: I have bloody marrys and I am seeing same numbers as the OP almost. Out of 50 shrimp kept 10. I am trying to see in 6-10 generations if all the good ones are kept if they will breed truer or if it is a lost cause

Having to disagree here, most mine have short rostrum and a different body figure, doing fine and breeding well, I'm seeing some bad colored ones but few young showing good redness like 1 week into birth.

I noticed that there are different grade of bloody mary on the market.

the seller told me that his bloody mary is about 80% breed true. he sells high grade bloody mary only.

High grade bloody mary has deep red color.

but regular bloody mary has brown patch on the body, or not that deep red.

Brown patch? I have some darker bloody marys, which makes them look fantastic compared to the other reds, unsure if that's what you mean. I have heard of some people's BM turning darker and eventually looking more black/rusty than red. Didn't see pictures but they said maroon colored.

Look it up c sky is the ones that started the whole marketing ploy with short Rostrom. You kind find it on facebook about breeders complaining about it and all over German forums and Japanese.

I bought high grade ones and I am on my first set off off spring old enough they gave birth and still maybe a high off 20% blood Mary and the rest suck. I paid 20$ a shrimp for mine.

Got mines from a reputable seller here, 8/ea, but that was recently. Indeed short rostrum, I need to wait for my shrimplings to grow out more before I comment on their appearance.

Wait, that last picture, yellow/orange eggs visible through shell? It's suppose to be like that for bm? I usually can't see it like that, only notice if berried if they're sitting there fanning or notice a shrimp has gained weight.
