PURE RED LINE PRL CRYSTAL SHRIMP - GOOD QUALITY

Pure Red Line (PRL) shrimp are a selectively bred variety of Caridina cantonensis, prized for their deep red and white colouration and genetic purity. Unlike standard Crystal Red Shrimp (CRS), which may have black gene ancestry from Crystal Black Shrimp, PRLs are bred exclusively from red lineage stock and never crossed back to black variants. This selective breeding ensures that PRLs consistently produce red offspring, with no risk of black colouration appearing in future generations—a common possibility with standard CRS.

Unlike standard Crystal Red Shrimp, Pure Red Line (PRL) also exhibits more beautiful and vibrant colours, in addition to purer genetics.

They are valued higher in the shrimp-keeping community for their stronger colours, purity, genetic stability and lineage. Their vibrant colouration and predictable genetics make PRLs a premium choice among shrimp hobbyists.

Not all Pure Red Line (PRL) shrimp are the same.

The PRL shrimp offered by Aquarzon here originates from a high-grade lineage of many years with solid and strong colours.

They are all healthy, and the size offered is also good. They are juveniles/subadults, usually within the size range of 0.8cm to 1.4cm (1.0cm average).

Shrimp orders are shipped Express on Monday/Tuesday on their own. If ordering plants/supplies, they will be shipped in seperate boxes.

Ideal Shrimp Water Parameters

The above is a general guide and the ideal levels. Usually, most shrimp can tolerate some variance if it is not too much or too sudden.

For example, Bloody Mary shrimp's ideal PH is 6.8 to 7.5, but they can usually be kept fine at a lower PH of 6.0 as long as it is relatively stable.

Likewise, while the ideal PH for PRL shrimp is 5.5 to 6.2, it is usually fine to be kept at a higher PH of 6.5 too as long as it is relatively stable.

The same applies for TDS.

For beginners, Bloody Mary shrimp are easier to keep due to their adaptability. As for PRL or Blue Bolt shrimp, which are more sensitive and require stricter water control.

To measure PH and TDS, we offer easy digital PH and TDS pens which can measure very fast. For temperature, we have a stick-on semi-transparent thermometer for easy 24/7 viewing. We also offer test strips which measure GH, KH and ammonia. All of these can be found at our Shrimp Care section.

Recommended Food & Plants

The sinking spirulina algae wafer is excellent for shrimp. Besides being highly nutritious, it does not degrade quickly, so shrimp have sufficient time to slowly snack on it.

The Australian cuttlebone provides calcium supplementation, which strengthens the shrimp's shell and protects against moulting issues.

The recommended plants for shrimp are mosses and smaller plants.Mosses such as Peacock Moss, Christmas Moss, Flame Moss, Giant Willow Moss and US Fissidens are excellent as shrimp love to forage on them for natural biofilm and infusoria, which is a natural food source for them.
