To start off your Pure Red Line (纯系) breeding program without golden (white shrimp) recessive genes, the best way to send them for DNA test. But.... thats the practical, here, is another method that can be carried out to validate your Pure Red Line breeding stock carries golden genes. Golden CRS offshrings can appear after many generation of breeding if the inital breeding stock is not tested even without intensional introduction of golden genes.

Golden genes in Pure Red Line is deemed undesirable by majorities in communities around the world. 

The method as follow: 
- Pair A: PRL female with a golden male
- Pair B: PRL male with a golden female

If Pair A has no golden offsprings but all red offsprings, then the female in Pair A does not has golden genes.
If Pair B has no golden offsprings but all red offsprings, then the  male in Pair B does not has golden genes.

After you have comfirm both PRL of different sex has no golden genes, put these 2 together to breed, the offsprings are comfirmed not to carry golden genes, so will be the offsprings' offspring.

The chances of these 2 to breed out golden offsprings, the chance of it will be extremely remote, just like striking a $10mil lottery, but this time, the breeder get no prize.

Often one can hear that his TDS meters are not measuring correct. One reason is it need recalibration, one will need calibraion solution to do this. Another reason is, basically TDS meters from different manufacturers are calibrated with different conversion factor.

TDS meter base on reading the conductivity of the water and convert it to TDS with a known conversion factor, it is known to be a conductivity meter of 200uS has a TDS value of 100ppm of NaCl. So very simple for manufacturers, they just get the meter to show the conductivity meter value by half and now become a  TDS meter. But some manfacturers use CaCO3 solution to calibrate and this will result in for the same water, the TDS values are different.

To avoid all the confusion, one can simply use a conductivity meters, and most TDS meter comes with conductivity measuring function.

See these golden crs or snow white shrimps with blue tint on rostrum? Golden CRS with such trait has the king kong genes. Cross this shrimps with a king kong and you will get some king kong babies.

Discuss here.

What can a king kong shrimp be when it gets all black? That all be the end of the trend, the new trend will be reversed, a mosura pattern like this will lead the trend.

Rili Shrimp is one of the most exciting development after King Kong Shrimps, this shrimp paths the way which neocardina shrimps can be developed into pattern strains rather then color strains only.

The Rili Shrimp in the picture is 3 of the most unique speciment in a Taiwan farm, this shrimp has clear body and intensified "painted" red on the head.

There are only 2 such pieces in the farm and the third one, I would say is the most unique neocaridinal shrimp developed so far. I shall up my blog on it soon. In the meantime, visit my gallery for pictures of Rili Shrimps. Finally, I got the gallery password fixed!

Ok, these are not siamese quadruplets, but gangbangs. 3 males trying to molted females. The female is huge and rather weak, this should be her 4th time into carry eggs.

This question is often hear in forum.

Long term external factors have great influence on CRS color beside the phenotype genes of a CRS:

• Water temperature, ideally is 23°C, this gives the best color vs other factor like growth rate. 24°C to 25°C will work as well, but 26°C and above is not so much for color.
• Light, there are 2 factors to consider, that is the invisible light and the visible light. A light temperature like in range of 10,000k will give better coloration for our eyes. And for invisible light, they will need those has UVB.  I like to use 2 combo from Sera light tube, the 12,000K Blue Sky and Sera Terra FL tube (full spectrum daylight with 30% UV-A and 4% UV-B).
• Food, plant based food like Mosura CRS Specialty food. "Meat" based food is better for growth rate while plant based food is better for coloration.
• Water pH, keep at round 6.5 to 6.8. Lower pH will give not so nice color.
• Water GH, around 6 to 8. Use Mosura Mineral Plus to increase mineral contents and GH.
• Less water change and change lesser amount of water.
• And of course good filtration of water, use canister filter and quality filter medium

The latest development in Wine Red Shrimp are pattern and color. The color is very deep red, often called as Blood Red and the pattern wise, it has yet to reach a common concensus in different communities. But vintage pattern like hinomaru seems to have won the heart of Taiwan community, Japanese community current is at liost of which trend to go, to go for more red patch or go for pattern, but I think they will go for pattern/color trend of Wine Red Shrimp instead of red patch trend soon.

The above picture shows a Blood Red Hino type of Wine Red Shrimp in focus and the rest are Wine Red Shrimp.
