The crystal red shrimp is a red mutation of the crystal black shrimp. Most hobbyists refer to crystal red shrimp as CRS. The CRS is not what we consider an entry level shrimp. When a hobbyist is making the transition from beginner to advanced, he or she will normally start with the CRS. The reason being is the CRS requires specific water parameters. They prefer a lower ph although not as low as one may think.
Currently, we house three small colonies of crystal shrimp. The grading scale for CRS in order of highest to lowest: SSS, SS, S, A, B and C. The higher the grade (SSS), the less red the shrimp will have. So, a C grade shrimp will be almost all red while an SSS grade shrimp will be almost completely white. This is the basic grading, the grades are broken down further but we won’t go any further. The shrimp we sell are A to S grade.

Caridina Shrimp Care:

Recommended :
PH: 6.5–7.0
TDS: 100–180
Water temp: 18-22C
Our Tanks :
PH : 7
TDS : 200
Temp : 21C
*Note: Our parameters are listed here for your reference only. You do not need to adjust your water to exactly the same; we find stable water is more important than exact parameters.

Provide a variety of leaf litter for the shrimp to graze on. Their primary food is the micro-organisms that grows on the submerged leaves. A natural environment with leaf litter, mosses and plants provides the shrimp with everything they need for a staple diet. Feeding commercial foods should be seen giving a treat, not a regular meal. Feed sparingly. Feed fresh leaves such as spinach, nettles and dandelion.

Live Arrival Guarantee:
Should a shrimp die during transport, we will refund the cost of this shrimp. In such a case please inform us within an hour of delivery with a picture of the dead shrimp. If there was extensive damage to the packaging, we would be grateful for a picture of the box as well.

Please acclimatise them slowly in a container over a period of several hours, mixing your tank water with the water they came in, slowly increasing (drip with airline) the amount of tank water until you have a mixture of 1/3 transport and 2/3 tank water. After that net them out and put them into their new home. It is normal for the shrimp to lose a little colour during transport. Shrimp will lose some colour due to transport, but will colour up after acclimating to their new homes
