Oh well, unnatural or not, has given me something to aim for! :thumbsu:

 

LOL!!! The only way to achieve that is to selectively cross-breed CRS with Snow White (not golden bee)/Mosura Panda and Wine Red. If this is the sort of CRS you are looking for, you could give this cross breeding method a try and you will be able to achieve it in 6 months. ;)

 

Also if you look at the colour of the net, it is showing as cyan/turquoise colour. This shows that the photo has been meddle with the white balance to make the white looks whiter. Hence, the actual shrimp will look much more yellowish. Below is a version of I adjusted the white balance. Due to the picture was overly exposed, the shell looks perfect. This is one of the common deception of the photos circulating on the net. Because of the camera or phone camera unable to capture the details, the shrimp shell will look smooth and constant colour. End up many people believe a normal CRS as a PRL. It is kind of hilarious at times.

Good example picture of full white antenna. Even the thin antenna part has some white in it. For me this pictures was jaw dropping too when I saw it for the first time. Something to aim for, was my response too :wink:. There might be some editing done, but it's seems not be over exposed because you can still see the lines between different segments.

 

Taking pictures of shrimp is still challenging for me too. You can always argue about them. A shrimp looks different below a big flashlight than a little aquarium tank light. Different color temperatures etc. So I always tell people not to go after a pictures but see them in real life. Sometimes I send people a low light/quality picture to give them a better impression.

 

Also I truly believe that the shrimp adept to their light source. A lot of bright light seems to have a positive influence on the shrimp color and thickness.

 

Even top class photographers images can be a source of discussion. The pictures of Ellen Wang shrimp taken by Chris Lukhaup. Just amazing, the red looks so bright and nice. But I can tell you, I've seen them a couple of times in real life on shrimp shows and the red is 'just like' the red of other shrimp, nothing different if you ask me.

 

But not only the colors, also the details of course on a macro pictures are different. So try to separate them. (Macro) photo's are amazing to look at and show us the beauty of shrimp at a particular moment in time and with a particular light source. In real life you enjoy their appearances, behavior and development over time. I hope you understand what I'm trying to say :D.

 

BTW, about MK-breed, I also found this picture. A very bright (this images is indeed over exposed) snow white. Maybe this genes has to do something with it. Not golden, but true snow white. Maybe from a Crystal Black string by selecting.

Now that is absolutely gorgeous! The white is full as it should be and the red on those legs, beautiful!

 

I'd hate to imagine how many generations were involved to get to that stage.

Doubt you'll find anyone with good quality shrimp from any Taiwanese farms.

1. They lack proper equipments to take such pictures if they did have a good shrimp.

2. They don't have said good shrimp.

Always nice to dream big though [emoji3]

What a great write up! And these images are amazing!

 

I am loving the comparison of colours.

 

I can now see why these are such a goal shrimp for many to aspire to!

Dude.... What are you talking about...

 

When they are in Japan and Hong Kong, they always join the Chinese with the "Big Canon Camera hang-on the Neck" Tourist Gang. Hence, I doubt they don't have camera.

Funny thing... This is exactly what I saw... So many older men with HUGE cameras and lens around their neck.. God I bet that lower back pain is unbearable, poor tourists.

Nice topic this is, even with all the side discussions, I like it. Informative for me too.
Sorry I can't keep up the posts every week, very busy period at the moment :wink:

 

This time I was going to show something that ShrimpDaddy point me to. It's about colored swimminglegs or pleopods as they are called. A good characteristic in my opinion is that as much as possible parts are colored. As showed before, this is much more intense that on 'normal' crystal red. Like the legs and the antenna's.

But even some of them has colored pleopods.

 

I've been camping in front of my tanks, but so fare I only have one picture from Shrimp Daddy to prove this colored pleopods:

Very nice example!

 

So you have to be patient for more pictures about this, and if I will not succeed, next post (in the new year!!) will be about abdomen, abdominal somietes.The panser of the body and the thickness and form of it.

This time I would like to show you something about the second abdomen or "breastplate" or "Tigerschaufel". This is a really awesome phenomenon that you only find on high quality PRL. To be honest, I don't have them myself. So I asked Mario Portera (Calls his shrimp JustBee, I got my shrimp from him) from Germany if I can show his pictures of some stunning pieces he have.

 

med_gallery_1170_14_317754.jpg
 
So far I know, you can only see this on female shrimp. When the shape is round and big and fully covered it has a great effect on the appearance of the shrimp. I believe a lot of the shrimp have the shape, but because they are not fully colored, it looks like it's small.

 

Examples:

If you can read German, you can check this analysis from Lisa Klotz:  http://www.crustahunter.com/wp-content/uploads/2014/10/FBA-Lisa-Klotz-Tigerschaufel.pdf or you can just look at the pictures ;).
 
And don't forget to check out Mario's website for more awesome shrimp: http://akaebinosato.de/gallery/
 
I'm not sure what to discuss next time. Most parts are covered so far. If you have a suggestion, please let me know.

Yes, that's a signature of good breed. Usually those with the "breast-plate" are close to competition grade. ;)

 

If you ever see it in person, the body shape is like a butterfly with folded wing. :D

The "breastplate" or "Tigerschaufel" is not only applicable for PRL/JRB, right? I have a few Ruby Red Taiwan Bees with just BEAUTIFUL Tigershaufel and i've also seen other Taiwan bees with this exact characteristic. I've often considered it's something that develops as adult females age and their clutch develops and expands bigger to enable larger brood, but in hindsight, I don't see this trait in 100% of my Taiwan Bees,

True. Also some of my Neocardina have a very beautiful thick and large Breastplate.

But among 'normal' Crystal Red, I've never seen something that's even close to the pieces in the photos in my last post. So your right it's not a special PRL thing, but according to PRL, I believe this is something that you only see on high quality pieces.

 

More interesting is, how to achieve this. Some people say by selecting, others say by coincidence. I will let you know when I've got the answer. Or if somebody know this, tell us please :wink:.

It is applicable for all shrimp. However for PRL/ JRB, they are selectively breed till it is very big. Due to the lighting, it is very hard to capture on camera; at least for me. If you see it in-person, you will be amazed by the shape, size and proportion of the second segment. Hmmm.... Not sure how to describe it. It is more like the length of the second segment is almost equal to the total length of the rest of the segment. This make them looks like perfect curve when they are in alert posture. If she ever comes out, I will try take a picture of her side.

 

You will understand once your young JRB/JBB is berried.

I have an update about the colored pleopods. I came across this picture of JF Lee. It's a mobile phone picture I guess, so colors are not realistic. Hence you can see that it's good quality, but what especially got my attention are the colored pleopods. This is a good example, got red and white into it. Very nice.

what about the actual red sections of the body on a PRL, How Solid should they be?

I mean if you had a A-S grade pattern on a PRL what would it be like depth wise?

      Shrimp and meds containing gentian violet

      By ngoomie · Posted

      Alright, I've done a bit more research on gentian violet's cancer-causing potential but I haven't yet done research on malachite green's to compare. But from reading the California propositon 65 document about GV (North Americans incl. some Canadians will recognize this as the law that causes some products they buy to be labelled with "known to the state of California to cause cancer", including the exact product I bought) it seems that the risk of cancer is related to internal use, either injection or ingestion. Speaking of ingestion, I think GV bans mainly relate to its use in treating fish/shrimp/etc. which are intended for human consumption, because of the above. And in countries where GV isn't banned for this purpose, it does seem to get used on various species of shrimp without causing any issue for the shrimp themselves (at least enough so for shrimp farming purposes). See the following: In February, the FDA Began Rejecting Imported Shrimp for Gentian Violet and Chloramphenicol (2022 article by Southern Shrimp Alliance) FDA Starts New Calendar Year by Refusing Antibiotic-Contaminated Shrimp from Three BAP-Certified Indian Processors and Adding a BAP-Certified Vietnamese Processor to Import Alert (2024 article by Southern Shrimp Alliance) Southern Shrimp Alliance and some other organizations have tons of other articles in this vein, but I'd be here for a while and would end up writing an absolutely massive post if I were to link every instance I found of articles mentioning shrimp shipments with gentian violet and/or leucogentian violet registering as contaminants. That being said, I know shrimp farmed for consumption and dwarf shrimp are often somewhat distantly related (in fact, the one time a shrimp's species name is listed that I can see, it's the prawn sp. Macrobrachium rosenbergii, who at best occupies the same infraorder as Neocaridina davidi but nothing nearer), but this at least gives a slightly better way of guessing whether it will be safe for aquarium dwarf shrimp or not than my bladder snail anecdote from the OP.

      Shrimp molting before eggs are hatched

      By sdlTBfanUK · Posted

      I would hazard a guess that perhaps those eggs were unfertilized and thereby unviable? Did the eggs change colour, usually yellow to grey as the yolks used up, or any eyes in the eggs. Is your water ok, using RO remineralised and the parameters in range, as I have heard others say that if the water isn't good it can 'force' a molt? How is it going overall, do you have a good size colony in the tank, you may have reached 'maximum occupancy' as a tank can only support so many occupants.

      Shrimp molting before eggs are hatched

      By beanbag · Posted

      Hello folks,  The current problem I am having is that my Taiwan bee shrimp are molting before all their eggs have hatched.  Often the shrimp keep the eggs for 40+ days.  During that time, they lose about half or so, either due to dropping or duds or whatever.  Shortly before molting they look to have about a dozen left, and then they molt with about half a dozen eggs still on the shell.  Then the other shirmp will come and eat the shell.  These last few times, I have been getting around 0-3 surviving babies per batch.  I figure I can make the eggs hatch faster by raising the water temperature more (currently around 68F, which is already a few degrees higher than I used to keep it) or make the shrimp grow slower by feeding them less (protein).  Currently I feed Shrimp King complete every other day, and also a small dab of Shrimp Fit alternating days.  Maybe I can start alternating with more vegetable food like mulberry?  or just decrease the amount of food?

      By ngoomie · Posted

      Yeah, cancer risk was a thing I'd seen mentioned a lot when looking into gentian violet briefly. I kinda just figured it might only be as bad as the cancer risk of malachite green as well, but maybe I should look into it more. I've been doing a pretty good job of not getting it on my skin and also avoiding dunking my unprotected hands into the tank water while treating my fish at least, though. Maybe I'll just not use it once I'm done this course of medication anyways, because I know a store I can sometimes get to that's pretty distant carries both malachite green and methylene blue, and in pretty large quantities.

      Can't help you with Gentian Violet, sorry. It is banned in Australia violet for potential toxicity, and even possible cancer risks. I thought it was banned in Canada as well. At least, you now know why there isn't much info on gentian violet medication and it's use. But keep an eye on the snails after a week. If it affects the snails, it might not kill them immediately. So keep checking for up to a week. Much safer options out there. No point risking your own life over unsafe products.
