Thread: Crystal Red Shrimp + Crystal Red Shrimp = CRS/Diamonds?

    Default Crystal Red Shrimp + Crystal Red Shrimp = CRS/Diamonds?

    Hi everyone!

    I've just started keeping these lovely shrimps and have a query where breeding is concerned: will a pure red crystal red shrimp tank result in both red and diamond shrimplets? Or will the baby shrimps all be red like their parents?

    Would appreciate some ideas / reference materials on this topic, thanks!

    Warmest regards,
    amidala

    P/S: Cool emoticons, by the way! I'm so spoilt for choice!

    Hi,
    let:

    b be red recessive
    B be black dominant (diamond/bee shrimp)

    When you cross:

    Rxb=Bb+Bb+Bb+Bb -> all are black

    Bbxb=bb+Bb -> 50% are black, 50% are red

    bxb=bb+bb+bb+bb -> all are red

    Bb still appears as black because this individual has only one recessive allel but both recessive allel are necessary to show the red phenotype.

    So you question, does crystal red shrimp cross crystal red shrimp will give diamond/bee (black), theoretically, it is not possible.

    I hope to understand the genetics of crystal red shrimp breeding better. I am currently in the process of setting up a crystal red shrimp breeding system and am looking for help in understand the dominate and reccessive characteristics allready identified. All 10 of my starter stock are siblings from the same brood.

    Please also help me to understand what a "Diamond" is

    Thanks

    According to the species page on this site, a diamond shrimp is what it's called in Singapore/Taiwan/HongKong or in the US and Europe it's called a bee shrimp.In other words, for gnatster and retardo a diamond shrimp =
    bee shrimp. So depending on where you're from, the same shrimp is called a different name. Hope I explained this right,
    John

    Yes John, you are right. That's why I want to standardize the way to call these shrimps using:

    http://www.shrimpnow.com/forum/showthread.php?t=189

    Understand that Diamond/Bee shrimp is still rare is USA, they are more scarce then CRS, so now so-called bee shrimp is unlikely Diamond/Bee shrimp.

    If diamond shrimps are bee shrimps, then why is bee shrimps so cheap but diamond so expensive in singapore. I've seen diamond and bee being sold in the same shop but with a significant price difference

    Thanks for all your replies, folks. Particularly with reference to fruitpie's suggestion of the use of different terminology to differentiate the Diamond/Bee from the Bee/New Bee.

    So am I right to say that if I wished to breed only CRS (i.e. only red & white banding), I should not mix the Diamond/Bee with the crystal red shrimp?

    Thanks for clarifying!

    Please read this thread for the naming convention:
    http://www.shrimpnow.com/forum/showthread.php?t=189

    Diamond/Bee does not means Diamond or Bee, nor it means diamond is bee shrimp.
