Grading Crystal red shrimp ?
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 ?

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".

Only people in SEA would be obsessed with the grading of shrimps, I don't see it so often this part of the world.
I think that it is our upbringing that causes this, wouldn't you agree?
There is nothing wrong with this though, just that to me, all shrimps are beautiful, and some people are just luckier than others in possessing more varieties and in colours as well ~nudge nudge wink wink @ Mustafa~

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.Petshrimp.com wrote:Hi Marge,

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 labourPetshrimp.com wrote: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.

Is this correct? Is the natural sex ratio in shrimp 1:1?Oqsy wrote:each shrimp has a 50/50 chance of being male, and the same for female... it's like tossing a coin...
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.

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.Is this correct? Is the natural sex ratio in shrimp 1:1?
