Hi,
I have the following CRS.
It look sort of different from the usual CRS.
Is it of a poorer grade ? Or is it due to a genetic defect ?

It looks like a normal crystal red to me...just more red than white. Crystal Red shrimp can be pretty variable.

I think they look better with more white though the ones I have are more clear then white. Or is this just like the whole blue thing saying blue when its really gray?

amber2461: Thanks

... I hope they will breed soon.
Mustafa: Why does mine look more brown than red ? The photo on your website is red.
I have 3 of them. How do I tell the Sex apart ?
What is my chances of getting a male or female ?
33.33% ?

your chances of getting a "male or female" out of 3 shrimp is 100%
each shrimp has a 50/50 chance of being male, and the same for female... it's like tossing a coin... trying to predict the sex with percentages is pretty much useless at such a small number. it's quite possible that you have 3 males or 3 females, just as it's not a rare thing to flip a coin and get heads 3 times in a row. it's only in the longer term (or larger numbers) where the 50/50 rule becomes more concrete. Based strictly on random chance as opposed to anatomic differences, I'd stick with the first statement I made... you have a 100% chance of having a "male *or* female".

Hi Marge,
I don't think it's the upbringing. After all we have so many people here in North America, who are obsessed with different colors and "grades" of guppies, different breeds of dogs, cats, horses etc.
As to getting different shrimp.....it took a lot of time, effort and money to get my collection together and I am still *FAR* from done.

Yes, but I think most hobbyist here are not so competitive when it comes to shrimps , not yet anyway.

We all await the day when you add more shrimps under your Buy Shrimp column so that the rest of us can enjoy the fruits of YOUR labour

Is this correct? Is the natural sex ratio in shrimp 1:1?
In a species that is not pair-bond-forming and shows no parental care, it is not uncommon for the ratio to be skewed towards females. Further, in many species, enviornment factors can have a great effect on the ratio of males to females. Apistos are notorious for this.

The old saying "Beggers can't be choosers." comes to mind.

you're probably right... i was just speaking in generalities... I have no knowledge whatsoever of the true ratio of any species of shrimp in terms of male:female... the point I was trying to make was that 3 is a small enough number that expecting a pair would be quite possible, but not guaranteed.
