Crystal shrimp are very colorful and attractive. The group swimming in the tank is quite spectacular, but keeping crystal shrimp is not a simple matter. Crystal shrimp individual small, like to eat some algae or aquatic grass shoots and corrupted organisms carcasses, afraid of high temperatures, can not tolerate high temperatures of more than 28 degrees, the requirements of the water quality is very strict, the slightest error will be too late to regret. In order to raise good crystal shrimp PH should be controlled between 6.0-6.8, hardness GH 4-6. The hardness of GH 4-6, but the crystal shrimp eat a lot of food, it is difficult to maintain the water quality in general. Magic Sand is a kind of bottom sand developed mainly for crystal shrimp and aquatic plants, which can clarify the water body quickly. The sand particles of Magic Sand collapse slowly, which can stabilize the water quality in the range of PH 6.0-6.5, GH 4-6, and can be maintained for a long period of time. And it is especially worth mentioning that the magic sand can adsorb organic phosphorus in the water, which has a strong inhibitory effect on the growth of algae The following is a set of crystal shrimp shrimp aquarium tank placement process: Choose a 45X35 small tank, the first has been sterilized by soaking in potassium permanganate for 30 minutes, and then washed with water, and then placed on a flat and stable tabletop. Lay the sand on a flat and stable table. It is important to note that the magic sand should not be placed too much, so that it will not play a good filtering effect, the main thing is to pay attention to the right amount, paving has the advantage of maintaining water quality Using external filtration, filtration of the water inlet with filter cotton wrapped in a circle, to prevent the crystal shrimp sucked away. Place a thermostat and set the temperature at 25 degrees, in summer it is better to add a cold water device. Add water that has been aerated beforehand, and do so gently. Add sedum and water plants and fossilized rocks. Set up the aquascape. After setting up, put the top light on the tank. Put the crystal shrimp into the tank. Stick on the background plate, finished! The arrangement of the crystal shrimp tank at the same time also feel an aspect of the magic sand --- ultra-fast water purification speed, compared to the previous bottom sand, add water and then have to add some activated carbon in order to quickly make the water clarify, and the magic sand easily and calmly completed this work! The crystal shrimp are in good condition after entering the tank, it's really comforting to see the little shrimp stringing around! (Red Crystal Shirmp) appeared in Japan began in the mid-1990s, rainbow diamond shrimp after the Japanese people a long breeding and many generations of purification, stabilized genes. So that the red recessive gene was maintained, and it became today's crystal shrimp. The color of the Crystal Shrimp is the same as Japanese Koi! Because of its red and white body color and become a high ornamental value of the aquarium creatures, only a few amateur players can do a small amount of breeding, most players are still from the shrimp dealer to buy.
At present, the crystal shrimp genes have been very stable, so the red crystal shrimp born must be red, its life expectancy of about 15 months, shrimp to adult shrimp in about 4-6 months, the mature female shrimp is generally about 20 ~ 30 eggs (3cm long female shrimp can hold 60 eggs), but not 100% hatching.
Domestic to Jiangsu, Zhejiang, Beijing and Tianjin, the northeast of the three areas of the most prosperous, the formation of crystal shrimp in China's three more concentrated and distinctive gathering places. Crystal shrimp class division is clear, beautiful color, moderate feeding difficulty, breeding there are certain skills and other characteristics, making it in many aquarium creatures in the enduring classic species.
Crystal shrimp breeding if you strengthen its body astaxanthin Chinese name astaxanthin is also called super vitamin E (see [1]

Juvenile shrimp: 0.4-0.8 kg per ton of feed (survival rate increased by 50%) Usage time: the entire breeding period
Adult shrimp: 0.24 kg per ton of feed (survival rate increased by 50%) 0.24 kg (survival rate increased by 45%, shrimp disease significantly reduced) Use time: 2 months before fishing
Spawning shrimp: add 0.75-1.5 per ton of feed (spawning increased by 40%) Use time: 2 months before spawning
How to better cultivate the crystal shrimp
1. Water quality (perfect water quality data exists)
The initial stage of shrimp farming .... There is always the feeling of powerlessness that the shrimp is getting less and less to use, to add all the additions, the female shrimp is also very smooth and continue to hold eggs in the number of shrimp is not as expected to increase, and every week or two or three hanging ..... In the clueless, one day the mind suddenly flashed a message, why each netizen shrimp feeding number from north to south and increasing (north soft south hard) Why Japanese players shrimp tanks are next to a large bucket and a large bucket of breeding water (so they looked for Taipei County tap water, groundwater, Taipei City tap water, and the tank of the breeding water to do an analysis of the comparison of when to buy back the GH, KH reagents home and read the manual) .... Finally, I realized that there is a breakthrough ~ it turns out that the water in Taipei City is too soft and too clean ~ not suitable for shrimp farming at all!
The two most important indices of water quality are General Hardness (GH) and Carbonate Hardness (KH). We tend to associate KH and omit the GH want to say are referred to the hardness, in fact, is not the same!
General hardness (GH) is the solubility of calcium and magnesium ions in the water, and calcium and magnesium is the highest demand for shrimp elements, so before the GH = 1.5 in soft water shrimp caused by incomplete shelling, hatching rate of survival rate is low, the cause of death is not clear the present situation! Supplements and other additives are no longer effective, in other words, less calcium! The most suitable general hardness is between GH=4~6 (TDS150~220)
Carbonate hardness (KH) and pH have an interactive relationship! As we all know... Organic nitrogen is produced by feces, bait and decomposition of aquatic plants in the shrimp tank to cause the most harm to the nitrogenous substances for the ammonia, it will decompose into nitrite, and finally the formation of nitrate, when the water PH is higher than 7 toxic ammonia will be produced, lower than 7 when the ammonia will be in the form of non-toxic form, ammonia, such as long-term shrimp tanks in excess of the standard value when... It means there's a problem with the biochemical filtration system! It will be harmful to the shrimp, so the most suitable carbonate hardness is between KH=1~2, pH=6.2~6.8
Then.... In the shrimp that I bought from Japan recently, I analyzed the water in each player's bag, and the result was the same as the value that I caught!
Summarizing the above arguments... In terms of tap water in the north... North city tap water PH=7 KH=1.5 GH=1.5 TDS=60, we just need to use black soil, and then pull up the GH... It's the best water quality condition! But how to raise the GH value? I use HAGEN's GH booster ~ it says "Mineral Additive"! It contains calcium, potassium, sodium, etc. .... It promotes ovulation and reproduction, and enhances the color! (This is a chemical enhancement method) If you want a natural enhancement method... For a natural enhancement, you can use Swarovski or Maifanshi. .... The amount must be very large... To be able to lift it! Too much sea mud is not good for shrimp oh!
2. Lighting
Lighting has a certain effect on the growth of shrimp later in life, browse the major Japanese shrimp network ... There are very few descriptions of light
Only Takayuki Shirakura mentions in his shrimp book that he uses UV halogen lamps and also 12000K lamps. And MFF almost always uses ADA HQI lamps for irradiation .... I also wonder if MFF is using ADA's 12000K saltwater lamps, while I'm using ZOO MED (ReptiSun 10.0 Linear Fluorescent UVB lamp ) UVB reptilian lamps! It helps in the formation of calcium in the shell, which means that the white part of the crystal shrimp will become thicker and whiter. If it is completely transparent... If it's completely transparent, it's impossible to get it back to white. It is possible to shine back to white drops!
3. Bottom bed
I still insist on shrimp tanks to lay a bottom bed to cultivate bacteria and physical filtration will be better after all, 70% of the shrimp's food source is microorganisms and minerals ingested in the water 30% is bait! So a sound nitrification system and a bottom bed to break down organic matter will help the crystal shrimp reproduce in the long run~
