Introduction to Blue Bolt Shrimp

The Blue Bolt Shrimp (Caridina cantonensis 'Blue Bolt') is a stunning Taiwan Bee variety, prized for its brilliant blue carapace that gradually fades into a pristine white body. Their coloration can range from an intense, deep blue to a lighter sky blue, often with varying degrees of translucency, making them a captivating centerpiece in any aquarium.

While Blue Bolt shrimp don't have a complex grading system, quality does vary. Higher-grade shrimp are identified by more extensive blue coverage and greater opacity. A solid blue color with a smooth transition to white is considered top-tier. These shrimp may have some white spotting, especially on the tail, but a smoother gradient is always preferred.

Like most dwarf shrimp, the Blue Bolt typically reaches a maximum size of about 1 inch (2-3 cm).

In a well-maintained aquarium with stable and optimal water conditions, these shrimp can successfully reproduce and have a lifespan of 1.5 to 2 years. However, as a Caridina variety, they require pristine water quality and are more sensitive than their hardier Neocaridina cousins, making proper care essential for their well-being.

Quick Notes on Blue Bolt Shrimp Care

These quick notes provide a concise overview for successful blue bolt shrimp care in any freshwater setup.

Natural Habitat of Caridina cantonensis

Blue Bolt shrimp are a selectively bred morph of Caridina cantonensis. This means you will not find shrimp with this specific coloration in the wild.

However, the wild Caridina cantonensis is widespread in southern China. They are found in areas like Nan'ao island, Guangzhou, Hong Kong, and likely northern Vietnam.

In nature, their preferred habitats are shallow, slow- to fast-moving mountain streams and rivulets. Wild populations face threats from habitat fragmentation, pollution, and collection for the aquarium trade.

The Behavior of the Blue Bolt Shrimp

Blue Bolt shrimp are fascinating to watch due to their active and social nature. They are not shy creatures and are often visible during the day.

These shrimp are completely peaceful and will not bother any other inhabitants in the tank. Their non-territorial behavior makes them a great choice for a calm community aquarium.

They are very social and prefer to live in large groups, which helps them feel more confident and secure. Within the group, there is no social structure or dominant leader.

Despite their small size, Blue Bolt shrimp are very agile. They can move quickly over short distances of 15 – 20 cm (6 – 8 inches) in the blink of an eye.

Comprehensive Blue Bolt Shrimp Care Guide

Successful blue bolt shrimp care relies on creating a stable environment where their specific needs are consistently met.

Tank Size Requirements for Blue Bolt Shrimp

While a small group may survive in a 5-gallon tank, a minimum of 10 gallons (~40 liters) is recommended. A larger water volume is more forgiving of fluctuations, simplifying the maintenance of optimal blue bolt shrimp water parameters.

Optimal Blue Bolt Shrimp Water Parameters

Maintaining precise blue bolt shrimp water parameters is critical for these sensitive Caridina shrimp. Always cycle your tank thoroughly before introducing them to allow the ecosystem to stabilize.

Summary of Optimal Water Parameters

• pH: 5.5 - 6.8

• GH: 3 - 6

• KH: 0 - 2

• TDS: 100 - 180

• Temperature: 20 - 22 °C (68 - 72 °F)

• Nitrate: Less than 20 ppm

Temperature Considerations for Blue Bolt Shrimp

Blue Bolt Shrimp prefer cooler water, ideally between 20-22 °C (68-72 °F). A heater may only be necessary if your room temperature fluctuates significantly or drops below this range, especially during colder months.

pH Preferences for Blue Bolt Shrimp

These shrimp require slightly acidic water with an optimal pH range of 5.5 to 6.8. Active or buffering substrates are highly recommended as they naturally lower and stabilize pH in this ideal range.

Importance of Hardness (KH & GH)

Water hardness is crucial for healthy molting. Maintain a KH (carbonate hardness) of 0-2 and a GH (general hardness) of 3-6. A very low KH is critical to prevent molting issues, but this can make pH unstable. Therefore, buffering substrates are essential.

Recommended Water Types and Minerals

For optimal blue bolt shrimp care, RO/DI (reverse osmosis) water is strongly recommended. Tap water often contains harmful contaminants. Since RO/DI water lacks minerals, it must be remineralized with products like Salty Shrimp GH+ to achieve precise control over water parameters.

Best Substrate for Blue Bolt Shrimp Tanks

Active or buffering substrates like ADA Amazonia aqua soil, Fluval Plant and Shrimp Stratum, or Akadama-Bonsai soil are essential. These substrates effectively lower the water's pH and stabilize it within the required acidic range.

Essential Filtration Systems

Sponge filters or matten filters are highly recommended for their efficiency, low cost, and safety for shrimplets. They also provide a large surface for beneficial biofilm to grow. If using other filter types, attach a pre-filter sponge to protect baby shrimp. Betta USA Aquatic offers a variety of suitable filters.

A sponge filter provides gentle and effective filtration for a shrimp tank.

Aeration Requirements

Blue Bolt Shrimp require good aeration to mimic their natural habitat of fast-moving streams. Adequate oxygenation is vital for their metabolism and overall well-being. Betta USA Aquatic provides essential air pump solutions to meet these needs.

Appropriate Lighting for Blue Bolt Shrimp

Lighting intensity is not a critical factor for the shrimp themselves. Instead, lighting choices should support the health and growth of any live aquatic plants in the tank. Explore suitable lighting options to enhance your setup.

Enhancing the Habitat with Decorations and Plants

Enriching the aquarium with decorations and live plants provides essential hiding spots and surfaces for biofilm and algae growth, which are important supplemental food sources.

Recommended Aquatic Plants for Blue Bolt Shrimp

Live plants enhance water quality and offer shelter. Recommended species include Water fern, Water wisteria, Anubias, Hornwort, and Java moss, as they naturally accumulate biofilm.

Recommended Decor (Driftwood, Rocks)

Driftwood and rocks provide critical hiding places for molting shrimp and foster biofilm growth. Always acclimate new decor carefully over 2-3 hours to prevent sudden changes in water chemistry. Discover a wide array of driftwood and rocks at Betta USA Aquatic.

Suitable Tankmates

The ideal situation for Blue Bolt Shrimp is a species-only tank, but they can be kept with other fish as long as those species are chosen with care. Avoid large and aggressive fish.

Due to their peaceful nature, Blue Bolt Shrimp should be housed with tank mates that are equally calm and share the same water parameters.

Compatible tank mates include:

• Shrimp: Crystal Shrimp, Bee Shrimp, Bamboo Shrimp, and Tangerine Tiger Shrimp.

• Snails: Japanese Trapdoor Snails, Ramshorn Snails, and Nerite Snails. Note that some snails may suffer from shell attrition in water with a pH below 7.0.

It is crucial to keep Blue Bolt Shrimp away from all types of crayfish and crabs, as they will attempt to catch and harm the shrimp.

Feeding Blue Bolt Shrimp for Optimal Health

Proper nutrition is fundamental to successful blue bolt shrimp care. As omnivorous scavengers, they naturally graze on biofilm and algae, but supplemental feeding ensures optimal growth and vitality.

Establishing a Feeding Schedule

Offer food once daily, or every 2–3 days in mature tanks. Provide only what the shrimp can consume within 3–6 hours, and remove any uneaten food to maintain pristine blue bolt shrimp water parameters. Using a feeding dish helps minimize waste.

A person carefully adds a small amount of food to a shrimp tank.

Risks of Overfeeding Blue Bolt Shrimp

Overfeeding degrades water quality, leading to dangerous ammonia and nitrate spikes and shortening the shrimp's lifespan. It can also trigger outbreaks of infections like Scutariella Japonica, Planaria, Vorticella, and Ellobiopsidae.

Sexing Blue Bolt Shrimp

There are a few key indicators to distinguish male and female Blue Bolt Shrimp, which is crucial for successful breeding.

• Size: Females are typically larger and more robust than males.

• Abdomen: A female's underside is wider and has a more curved shape to safely carry eggs. Males have a thinner, more streamlined abdomen.

• Saddle: Mature females may display a "saddle," which holds undeveloped eggs behind their head. However, this can be difficult to see due to the shrimp's coloration.

Breeding Blue Bolt Shrimp

Once you establish stable and suitable water parameters, Blue Bolt Shrimp will begin to breed naturally when they reach sexual maturity at 3–4 months old.

The process begins when a female molts, releasing hormones that signal she is ready to mate. This causes male shrimp to become highly active, swimming around the tank to find her. After mating, the female carries a clutch of 30–40 eggs under her tail.

She will fan the eggs regularly for 4–5 weeks to keep them oxygenated. The shrimplets hatch as miniature, fully independent versions of the adults, about 2mm long. Their coloration will intensify as they mature.

Crossbreeding and Interbreeding Blue Bolt Shrimp

It is important to know that Caridina species do not interbreed with Neocaridina species, so you can safely keep them in the same tank without risk of hybridization.

Blue Bolt Shrimp can also be housed with other Taiwan Bee varieties (like Black King Kong or Panda shrimp). Since they share similar genetic lines, they will not create unwanted hybrids and will produce offspring that look similar to the parents.

Molting in Blue Bolt Shrimp

Molting, the process of shedding an exoskeleton, is a natural part of a shrimp's growth. The frequency depends on age; juveniles may molt weekly, while adults molt every 4–6 weeks.

During this time, the shrimp will be less active and hide more. They are extremely vulnerable, so it is critical not to disturb them. Do not remove the old shell from the tank, as the shrimp will consume it to reabsorb essential calcium and minerals.

Common Diseases and Health Concerns for Blue Bolt Shrimp

Pristine water quality is paramount for blue bolt shrimp care. The most common health issues stem from high ammonia and nitrate levels, which cause stress, chemical burns, and death. Blue Bolt Shrimp are extremely sensitive to ammonia spikes. A robust filtration system, regular monitoring of blue bolt shrimp water parameters, and weekly partial water changes are essential.

Important: Never use copper-based medications, as they are lethal to invertebrates.

Common Mistakes to Avoid in Blue Bolt Shrimp Care

• Inconsistent Water Parameters: Failing to maintain stable pH, GH, and especially KH is a common pitfall.

• Sudden Water Changes: Large, infrequent water changes or improper acclimation can cause severe stress and mortality.

• Overfeeding: This fouls the water with ammonia and nitrate spikes, leading to disease and a shortened lifespan.

• Using Copper-Based Medications: These products are lethal to all invertebrates, including shrimp.
