EXTREME BLUE BOLT SHRIMP - HIGH GRADE

Extreme Blue Bolt shrimp are a stunning and highly sought-after variety of Caridina cantonensis, known for their intense blue coloration that ranges from icy sky blue to deep sapphire. What sets the "Extreme" grade from normal Blue Bolt apart is the vivid, full-body coverage of this striking blue hue, often with little to no white patches, giving the shrimp a bold, electric appearance.

These shrimp are the result of generations of selective breeding focused on enhancing both the color depth and consistency. In a planted aquarium, Extreme Blue Bolts create an eye-catching contrast against green foliage and dark substrates, making them a centerpiece species for shrimp enthusiasts. Like other Caridina, they require soft, slightly acidic water and stable tank conditions, and due to their rarity and visual appeal, they are often considered a premium-grade choice for advanced hobbyists looking to elevate their shrimp-keeping experience.

Not all Extreme Blue Bolt / Blue Bolt shrimp are the same.

The Extreme Blue Bolt shrimp offered by Aquarzon here originates from a high-grade lineage of many years with strong blue colour.

They are all healthy, and the size offered is also good. They are juvies/subadults, usually within the size 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.
