I have a couple questions that I couldn't find the answer to (definitively) by searching.

Have you ever seen a dark red CRS? The red is almost a maroon color.

Do breeding CBS with your CRS really intensify the white coloration, or is is just because CBS look more white because your comparing the white on the shrimp to a darker color (black) instead of a lighter color (red)?

Please if you have proof or actual first hand knowledge feel free to post but we really dont need any more hearsay or urban legends in the shrimp community.

dark red crs are fairly common as younger crs, the color tends to turn lighter with age. Sometimes mixing crs and cbs will make a reddish brown, but that will also turn either red or blackish.

mixing cbs with crs doesn't do anything except muddy genetics a bit. If you want strong strong whites, raise cbs which are actually whiter.

if you want really white whites and strong reds, look into getting some JPRL, which have never been exposed to goldens.

I'm talking a maroonish/purplish color. I have others of the same age/size that are normal colored. Ill snap a pic here in a bit.

I don't have any CBS in the tank but I have read that having them can make the white even stronger in all the shrimp. I'm very happy with mine but you know in the hobby it's just too damn hard to leave well enough alone!

Where would one go to view/purchase said jprl's?

you'd have to deal with someone reputable, I know the bay area has been flooded, so has the seattle area, with nonpure lines toted as real

So you or no one you know personally has a contact over there? I wonder if gabe would send some to me? His shrimp setup is very impressive and the resultant product he offers looks very high quality as well.

Liam and I both know someone who can get a hold of the JPRL. However, with that being said, they can be pretty expensive.

@Nikki, Do you know what the going rate on them is?

Anywhere from 50 and up per to get them shipped here. Price varies on exactly what quality you want. There are JPRL with pure red legs and some with pure white legs. It all varies.

and ever since gabe sold his school, I don't think he keeps a lot of shrimp anymore... I don't think that shrimp house exists anymore.

I thought I read somewhere that Gabe was out of the shrimp business.

he is, he's just a hobbyist now, last I heard from him, he had sold his english schools, shrump house and started working for the government.

Are we talking about $50 per SSS shrimp? I'm also thinking that they would have a minimum order criteria as well.

What is it exactly that makes these so great? Is is because they are from many different lines and do not have crossbred genetics?

$50 seems like a steal. I thought they were more like $1200-$1500 each!

As Liam said, they haven't been bred with snow whites, hence the 'pure.'

If you see a picture of them, you'll know why they're so special! The coloring is so perfect and vibrant that they look like little plastic toys.

No, not for an SSS. They JUST recently were able to breed SSS using JPRL. The highest you can go with a JPRL is typically SS. They SSS grades are EXTREMELY expensive.

That is a JPRL. They have full coloration on the legs, and the carapace is solid white. Unlike most of the CRS here, they have no "breakage" in the white at all. Because of this, they are highly sought after. And the prices for them can be exuberant.

There are indeed some that go for 1200-1500, but this is due to complete coloration of the legs, genetic qualities, etc... , and those are rarer then you think. You will get maybe 1 out of 300 that will sell for that. And when you do, you send that shrimp over to be auctioned to get that price.

Although, because goldens haven't been introduced, they lack any of the "flower" or "crown" patterns. However, those shrimp are the ones the usually fetch the 750-1500 range.

This shrimp sold for $850

$50 is more for the low grade JPRL.

Those sure are nice looking. But a stupid amount of money for sure. I have been assured that the shrimp I have weren't crossed with goldens/snow whites but I have no documentation.

I guess the jprl's are like prize winning show dogs. There is a paper trail that shows what shrimp were bred with what shrimp.

That would be fun to say "Yep, this is my prized stud here. I usually charge $500 per mating but I'm sure we could work something out"!!!

Pure lines will have no patterns in the head gear. No flowers, hearts, or crowns will appear. If any of those appear in your brood, then at some point in the line, goldens were introduced.
