Caridina profile
Blue Bolt shrimp
Caridina sp. Blue Bolt
Blue Bolt shrimp are blue-white Taiwan Bee-type Caridina. They are valued for soft blue tones but require stable soft-water conditions and careful line selection.
Quick verdict
Suitable for: Experienced Caridina keepers focused on stable water and selective breeding. Watch especially: adjust KH, GH and TDS slowly.

Important
Do not treat these as easy beginner shrimp. High-grade Taiwan Bee, Pinto and Boa lines need stable soft water, low KH, active substrate, mature biofilm and careful feeding. Avoid rapid changes, warm water, high nitrate, exhausted substrate and mixed-line breeding without a clear goal.
Care in practice
These are the points that most often make the difference between survival and a stable colony.
Use remineralized RO water with active substrate. A practical range is 19-23 degrees Celsius, pH about 5.6-6.6, GH 4-6, KH 0-1 and TDS roughly 100-150 ppm. Keep values stable and change water slowly with closely matched temperature and mineral content.
Use a mature, dedicated Caridina tank with active substrate, gentle filtration, moss, leaf litter and lots of biofilm. A protected intake is essential for shrimplets. Let the aquarium mature well before adding expensive breeding stock.
Base feeding on biofilm and small controlled portions of quality shrimp food. Use powdered food carefully for shrimplets and remove leftovers. Overfeeding is one of the fastest ways to destabilize a soft-water Caridina tank.
Keep a calm group with enough animals for breeding, usually at least 10 if budget allows. They are peaceful, but stress from fish, frequent disturbance or unstable maintenance quickly affects color, molting and breeding.
A dedicated shrimp-only breeding tank is the safest choice. Avoid fish and avoid mixing different high-grade lines unless you are intentionally planning crosses and tracking offspring.
These lines breed in freshwater with direct development, but reliable breeding depends on mature biofilm, low-stress conditions and stable soft water. Select breeding stock carefully and cull or separate animals that do not fit the line goal.
Common mistakes are buying expensive shrimp before the tank is mature, using unstable tap water, allowing KH or nitrate to rise, overfeeding, changing too much water at once, mixing lines without records and selecting only for pattern while ignoring health and fertility.
Background and identification
Extra context helps you identify, compare and keep the species safely.
These are selectively bred aquarium Caridina lines, usually built from Bee shrimp, Taiwan Bee and Pinto-related breeding backgrounds. Treat trade names as breeding-line names rather than wild species names unless exact lineage is documented.
Blue Bolt shrimp range from pale blue-white to deeper blue depending on grade and line. Clean color, healthy body shape and stable breeding are more important than color alone.
Blue Bolt shrimp share Taiwan Bee care with King Kong, Panda and Wine Red lines, but the visual goal is blue-white coloration.
Full species profile
Blue Bolt shrimp are Taiwan Bee Caridina selected for blue to blue-white coloration. They are sensitive and should be kept in a mature soft-water setup.
Appearance
The color can range from icy pale blue to stronger blue. Females may show deeper color, and line quality affects how even and stable the blue appears.
Water parameters
Use remineralized RO water with active substrate. A practical range is 19-23 degrees Celsius, pH about 5.6-6.6, GH 4-6, KH 0-1 and TDS roughly 100-150 ppm. Stability matters more than chasing a single exact value.
Aquarium setup
Use a mature dedicated Caridina aquarium with active substrate, gentle filtration, moss, leaf litter and protected intakes. Let the tank develop stable biofilm before adding valuable breeding animals.
Feeding
Feed lightly. Biofilm and microfauna are the base, with small amounts of quality shrimp food and occasional fine powdered food for shrimplets. Overfeeding can quickly destabilize soft-water tanks.
Behavior and tank mates
Blue Bolt shrimp are peaceful but sensitive. Keep them in a calm shrimp-only tank for best breeding results. Fish and frequent disturbance reduce shrimplet survival and can suppress breeding.
Breeding and selection
Blue Bolt grading can be subjective. Select for healthy, fertile animals with stable color rather than chasing only the deepest blue.
