    Hi guys

    I have googled it but get different answers...
    Some of my mature RCS have this very prominent white line down their backs. But other ones don't. What is the reason for this?

    Thanx
    Martin

    But its some of the old ones I bought. Only 3 or 4 of them. All my younger ones dont look like that. I have introduced some new strains very recently and started moving the best ones to another tank. So all should be fine. Thanx Jax

    As Jax says... the genetic trait for the stripe is becoming dominant in your gene pool due to a limited genetic variation in your gene pool of shrimp... Advice? Split the population to only have your pure reds together (+get some RCS from a different source to add to them) ... I kinda like the white stripe ones as well... try breeding them to make this a dominant trait and see how far it goes...

    PS: See you from Brakpan... could maybe be the water :p (sorry - couldnt resist...)

    That neon stripe, as I call it, is common in most neo varieties. They look great in the yellows..

    Sakura neos often have this stripe, usually referred to as fire reds or fire yellows and are selected and sold separately for more bucks :)

    When I get my next bloody shrimp rack up and make space I will selectively breed them, but have too many other shrimp plans at the moment..

    You're right about it looking great (neon) on the yellows! Are those photos of your stock Trev?

    I find when they hit maturity the females tend to get that stripe.

    Both sexes can get it, but sure mature females usually have the more intense colour.. those are mostly sub adults in the pic.. The neon stripe can be seen even when a couple of weeks old in both sexes. Good quality males can go a great rich yellow as well, as can be seen in the pic towards the back in the middle of the group.

    Same here. My nature females also have this.

    Finally have a separate tank to take the best out.
    But keen to read all about it Trev.

    yes, a simple petri dish, I have them in all my shrimp tanks, it minimises the food wastage from seeping into the ADA or substrate and hopefully maintaining better quality, the secret of all shrimp keeping. I would rather also maximise the food available for the shrimp and not encourage planaria and leaches to lurk in the substrate.

    Hennie, check out the young male with the neon stripe in the foreground.
