Red Hinomaru Shrimp

Caridina Red Hinomaru shrimp are striking freshwater dwarf shrimp prized by aquarium enthusiasts for their vibrant coloration and unique pattern. These small crustaceans feature a bold red spot on their backs, reminiscent of the red circle on the Japanese flag, hence their name “Hinomaru,” which means “sun circle” in Japanese.

Scientific name and classification:

The Red Hinomaru shrimp belongs to the genus Caridina, part of the family Atyidae. While often referred to as Caridina cf. cantonensis, their exact taxonomic classification remains debated among experts.

Origin and natural habitat:

Red Hinomaru shrimp are believed to originate from Taiwan. In their natural habitat, they inhabit slow-moving streams and rivers with dense vegetation and leaf litter. These environments typically have soft, slightly acidic water with temperatures ranging from 68-78°F (20-26°C).

Physical appearance, size, and lifespan:

The most distinctive feature of Red Hinomaru shrimp is the large, circular red spot on their otherwise white body. This spot can vary in intensity and size but typically covers a significant portion of the shrimp’s back. Some specimens may also display red coloration on their legs or antennae.

These dwarf shrimp are relatively small, typically growing to about 0.8-1.2 inches (2-3 cm) in length. Females are generally larger and more robustly built than males. In optimal conditions, Red Hinomaru shrimp can live for 2 years, though their lifespan in captivity can vary based on water quality and care. Their small size and peaceful nature make them popular additions to community tanks and nano aquariums.

History of Caridina Red Hinomaru Shrimp

The Red Hinomaru shrimp is a product of selective breeding, developed by dedicated hobbyists and breeders. The original stock likely came from wild-caught Caridina cantonensis specimens from Taiwan. Breeders carefully selected and paired shrimp with the most desirable traits over multiple generations, gradually enhancing the distinctive red spot pattern and overall coloration.

This process of selective breeding began in the early 2000s, with significant progress made in stabilizing the Red Hinomaru pattern by the mid-2010s. The goal was to create a shrimp with a clear, well-defined red circular patch on a predominantly white body, mimicking the Japanese flag design. Red Hinomaru shrimp are a pattern of Crystal Red Shrimp (CRS). 

Popularity in the aquarium hobby:

Since their introduction to the aquarium trade, Red Hinomaru shrimp have gained significant popularity among freshwater shrimp enthusiasts. Their unique appearance sets them apart from other dwarf shrimp varieties, making them highly sought after by collectors and aquascapers alike.

The rise of specialized shrimp-keeping forums and social media groups in the 2010s helped spread awareness and appreciation for Red Hinomaru shrimp. Their striking appearance makes them excellent subjects for aquarium photography, further boosting their popularity online.

While initially rare and expensive, successful breeding efforts have made Red Hinomaru shrimp more accessible to hobbyists in recent years. However, they still command premium prices compared to more common shrimp varieties, especially for high-grade specimens with well-defined patterns.

Caridina Red Hinomaru Shrimp Care and Ideal Water Parameters

Maintaining proper water parameters is crucial for the health and well-being of Red Hinomaru shrimp. These shrimp are sensitive to water conditions and require specific parameters to thrive. Here are the ideal water parameters for Red Hinomaru shrimp:

•    TDS (Total Dissolved Solids): 100-120 ppm
•    pH: 5.4-6.2
•    GH (General Hardness): 4-5 dGH
•    KH (Carbonate Hardness): 0-1 dKH
•    Temperature: 60-72°F (15.5-22°C)

To maintain these parameters:

1. Use RO (reverse osmosis) or distilled water remineralized with shrimp-specific remineralizes.
2. Perform regular water tests to monitor parameters.
3. Conduct small, frequent (every 1-2 weeks) water changes (10% weekly) to maintain water quality without causing drastic shifts in parameters.
4. Use buffering substrates designed for Caridina shrimp to help stabilize pH and mineral content.
5. Avoid overfeeding, which can lead to water quality issues.
6. Ensure proper filtration, preferably with low-flow sponge filters to avoid stressing the shrimp.

By carefully maintaining these water parameters, you can create an environment where Red Hinomaru shrimp not only survive but thrive and reproduce successfully.

Setting Up a Successful Caridina Red Hinomaru Shrimp Tank

Tank size recommendations:

While Red Hinomaru shrimp can be kept in smaller tanks, a minimum of 5 gallons is recommended to ensure stable water parameters. For a thriving colony, a 10-gallon tank or larger is ideal. Larger tanks provide more stable water conditions and allow for a larger population of shrimp.

Filtration options:

Sponge filters are the preferred choice for Red Hinomaru shrimp tanks. They provide gentle filtration that won’t harm or stress the shrimp while effectively maintaining water quality. Sponge filters also create additional surface area for beneficial bacteria and offer grazing opportunities for the shrimp. If using a hang-on-back or canister filter, cover the intake with a fine sponge to prevent shrimp from being sucked in.

Substrate choices:

For Red Hinomaru shrimp, an active, pH-buffering substrate is crucial. Avoid substrates like regular gravel or sand. Instead, use specialized shrimp soils such as ADA Amazonia, Fluval Stratum, or other similar products designed for Caridina species. These substrates help maintain the low pH and soft water conditions that Red Hinomaru shrimp require. The substrate layer should be 1-2 inches deep to allow for adequate buffering capacity.

Importance of hiding places and plants:

Red Hinomaru shrimp thrive in well-planted tanks with plenty of hiding spots. This setup mimics their natural habitat and helps them feel secure, reducing stress. Consider adding:

1. Live plants: Java moss, Java fern, Anubias, and Cryptocoryne species are excellent choices.
2. Driftwood: Provides hiding places and grazing surfaces.
3. Indian almond leaves: Offer additional hiding spots and release beneficial tannins.
4. Ceramic shrimp tubes or caves: Create safe molting spaces.

A densely planted tank also helps maintain water quality and provides additional surfaces for biofilm growth, a natural food source for the shrimp.

Acclimation process: Proper acclimation is crucial for the survival of Red Hinomaru shrimp when introducing them to a new tank. Follow these steps:

1. Float the sealed bag in the tank for 15-20 minutes to equalize temperature.
2. Open the bag and add a small amount of tank water (about 10% of the bag’s volume) every 5-10 minutes.
3. Repeat this process for at least an hour, preferably longer for sensitive species like Red Hinomaru.
4. Once the bag’s water parameters closely match the tank’s, gently transfer the shrimp using a net.
5. Avoid introducing the bag water to the tank to prevent potential contaminants.

For best results, consider using a drip acclimation method, which allows for an even more gradual adjustment to new water parameters.

After acclimation, monitor the shrimp closely for the first few days and perform regular water tests to ensure stable conditions.

Diet and Feeding

Natural feeding habits

In their natural habitat, Red Hinomaru shrimp are primarily detritivores and algae grazers. They constantly forage for biofilm, algae, and decaying organic matter on surfaces within their environment. Their fan-like appendages are adapted to filter tiny particles from the water and scrape food from various surfaces.

Recommended commercial foods

While Red Hinomaru shrimp can survive on the biofilm and algae in a mature tank, providing a varied diet ensures optimal health and coloration. Recommended commercial foods include:

1. High-quality shrimp-specific pellets or granules
2. Algae wafers
3. Specialized powder foods for dwarf shrimp
4. Freeze-dried foods like daphnia or bloodworms (occasional treats)

Look for foods that are rich in plant matter and low in protein to mimic their natural diet.

Supplemental foods: Offering a variety of supplemental foods can enhance the shrimp’s diet and provide environmental enrichment:

1. Blanched vegetables: zucchini, spinach, kale, cucumber
2. Dried leaves: Indian almond leaves, mulberry leaves, oak leaves
3. Flowers: dried hibiscus flowers, marigold petals
4. Snowflake food: dried food that expands in water, providing a grazing surface
5. Homemade foods: gelatin-based foods with added vegetables and supplements

These supplemental foods not only provide nutrition but also mimic the variety of food sources available in their natural habitat.

Feeding frequency and amount: Feed 2-3 times a week, an amount that the shrimp can consume within 1-2 hours. Avoid overfeeding to maintain water quality and prevent food from fouling the tank.

A good rule of thumb is to start with a portion about the size of a shrimp’s eye and adjust based on consumption. It’s better to underfeed slightly than to overfeed, as excess food can quickly foul the water.

Observing your shrimp’s behavior is key. If they immediately swarm new food, they may need more frequent feedings. If they show little interest, you might be overfeeding.

Remember that a mature, well-planted tank will provide a constant supply of biofilm and algae, which form a significant part of the shrimp’s diet. Supplemental feeding should complement, not replace, this natural food source.

Understanding Caridina Red Hinomaru Shrimp Grading

Basic principles of Caridina Red Hinomaru shrimp grading:

Grading Red Hinomaru shrimp is a process of evaluating and categorizing individuals based on their appearance and adherence to ideal traits. The primary factors considered in grading include:

1. Red spot quality: The central red spot should be well-defined, circular, and intense in color.
2. Body color: The base color of the shrimp should be a clean, opaque white.
3. Spot size and position: Ideally, the red spot should cover about 20-30% of the shrimp’s back and be centrally located.
4. Symmetry: The red spot should be symmetrical and evenly shaped.

Grading categories often include:

•  G3: These shrimp have lighter, less intense colors with more transparent areas on their bodies.
•  G2: Mid-grade shrimp show more solid and consistent colors but may still have some lighter or transparent patches.
•  G1: High-grade shrimp exhibit deep, vibrant colors with minimal transparency. The colors are solid and uniformly distributed. The legs are also fully colored
•  G0: Competition grade shrimp display the most intense and saturated colors with a flawless, uniform appearance, making them highly prized among breeders and collectors.

Grading plays a crucial role in both breeding programs and the commercial aspect of the hobby:

1. Breeding selection: Grading helps breeders identify the best specimens to use in their breeding programs. By selectively breeding high-grade shrimp, breeders can work towards improving the overall quality of their stock and developing more consistent, desirable traits.
2. Price determination: Higher-grade shrimp typically command premium prices in the market. Grading allows sellers to price their shrimp accurately based on quality and helps buyers understand what they’re purchasing.
3. Genetic improvement: Through careful grading and selective breeding, the overall quality of Red Hinomaru shrimp in the hobby has improved over time. This process has led to more vibrant colors and more consistent patterns.
4. Customer expectations: Grading provides a common language for buyers and sellers, helping to set clear expectations about the quality of shrimp being sold.
5. Culling decisions: In breeding projects, grading helps determine which shrimp should be culled (removed from the breeding population) to maintain or improve the quality of the line.
6. Hobbyist goals: For many shrimp keepers, working to produce higher-grade shrimp becomes a rewarding aspect of the hobby, driving engagement and fostering a deeper appreciation for the intricacies of shrimp genetics and breeding.

While grading is important, it’s worth noting that lower-grade shrimp can still be beautiful and make excellent pets. The grading system primarily serves breeding and commercial purposes, and all healthy Red Hinomaru shrimp can be enjoyable additions to an aquarium.

Factors affecting color intensity:

Several factors can influence the color intensity of Red Hinomaru shrimp:

1. Genetics: The most crucial factor. Higher-grade parent shrimp are more likely to produce offspring with intense coloration.
2. Diet: A varied, high-quality diet rich in natural color-enhancing compounds can improve and maintain color intensity. Foods containing astaxanthin and other carotenoids are particularly beneficial.
3. Water parameters: Maintaining optimal water conditions helps shrimp display their best coloration. Stress from poor water quality can cause colors to fade.
4. Age: Young adult shrimp often display the most vibrant colors. As shrimp age, their colors may become slightly less intense.
5. Lighting: While not directly affecting the shrimp’s true color, proper lighting can enhance the visual appearance of the red spot. Full-spectrum LED lights often bring out the best in Red Hinomaru coloration.
6. Background color: A dark substrate or background can make the white body and red spot appear more vivid due to contrast.
7. Molting cycle: Shrimp colors are often most intense just after molting when their new exoskeleton is fully hardened.
8. Stress levels: Any form of stress, including aggressive tank mates or frequent disturbances, can cause colors to fade temporarily.
9. Breeding condition: Females carrying eggs (berried) may display more intense coloration.
10. Tank environment: A well-planted tank with plenty of hiding spaces can help shrimp feel secure, potentially leading to better color expression.

Pattern Grading

Introduction to types of patterns:

While Red Hinomaru shrimp are primarily known for their distinctive red spot, there are variations in crystal red shrimp. The main pattern types include:

1. Hinomaru: The classic pattern, featuring a single, well-defined red spot on the back, resembling the Japanese flag. This is the standard and most recognizable pattern.
2. No Entry: In this pattern, the red coloration doesn’t extend to the head of the shrimp. The red spot starts further back on the body, creating a clear white “entry” area.
3. Mosura: Named after the fictional monster Mothra, this pattern features additional red markings on the head that resemble Mothra’s distinctive head markings. The main red spot may be accompanied by smaller red spots or streaks.
4. Full Red: Some shrimp may develop more extensive red coloration, covering a larger portion of the body than the standard Hinomaru pattern.
5. Snow White: A rare variation where the shrimp lacks any red coloration, appearing completely white.

Rarity and value of different patterns:

The rarity and value of different patterns can vary based on current trends in the hobby and the specific breeding lines. Generally:

1. Classic Hinomaru: This is the standard pattern and forms the baseline for value. High-grade Hinomaru with intense coloration and perfect spot placement are valuable but not the rarest.
2. No Entry: When well-defined, this pattern is often highly prized. A clear, sharp delineation between the white “entry” area and the red spot can increase value.
3. Mosura: Due to its distinctive appearance, Mosura patterns are often sought after by collectors. High-grade Mosura with symmetrical head markings and a well-defined main spot can be quite valuable.
4. Full Red: While not adhering to the classic Hinomaru ideal, some hobbyists appreciate the striking appearance of Full Red specimens. Their value can vary based on the intensity and coverage of the red coloration.
5. Snow White: As a rare genetic variation, Snow White Red Hinomaru shrimp (which are actually completely white) can be highly valuable to collectors and breeders looking to introduce this trait into their lines.

However, it’s important to note that value in the hobby can fluctuate based on trends, local availability, and individual preferences. A perfectly formed classic Hinomaru with intense coloration might be more valuable than a lower-grade specimen of a rarer pattern.

Breeders often work to stabilize and improve specific patterns, which can influence their rarity and value over time. As with color grading, pattern grading is subjective and can vary between breeders and sellers.

Breeding Caridina Red Hinomaru Shrimp

Breeding setup requirements: To successfully breed Red Hinomaru shrimp, maintain the following conditions:

1. Tank size: Minimum 10 gallons, larger is better for stable parameters
2. Water parameters: Match the adult care parameters (pH 5.4-6.2, TDS 100-120, GH 4-5, KH 0-1)
3. Temperature: 68-74°F (20-23°C) for optimal breeding
4. Filtration: Gentle sponge filter to avoid sucking up shrimplets
5. Dense plantings and moss for hiding places and foraging areas
6. Active substrate to maintain water chemistry
7. Mature tank with established biofilm for shrimplet food

Mating behavior:

1. Males will actively search for females ready to molt
2. After molting, females release pheromones attracting males
3. Males perform a mating dance around the female
4. Mating occurs shortly after the female’s molt when her shell is soft
5. The male deposits a sperm packet, which the female uses to fertilize her eggs

Egg development and hatching:

1. Fertilized eggs are carried under the female’s tail (berried state)
2. Eggs start dark and become lighter and more transparent as they develop
3. Incubation period: 28-35 days, depending on water temperature
4. Females fan their eggs regularly to provide oxygen and prevent fungal growth
5. Just before hatching, you may see eyes developing within the eggs
6. Eggs hatch in batches over 1-3 days
7. Newly hatched shrimplets are miniature copies of adults, about 1mm in size

Care for shrimplets:

1. No special care is needed; shrimplets can fend for themselves
2. Ensure sponge covers on all filter intakes to prevent shrimplets from being sucked in
3. Maintain stable water parameters; shrimplets are more sensitive than adults
4. Provide plenty of biofilm and algae for grazing
5. Supplement with crushed high-quality shrimp food or specialized powder food for babies
6. Avoid large water changes; do small, frequent changes to maintain water quality
7. Dense plants and moss provide shelter and foraging areas
8. Remove any predators from the tank (including some fish species)
9. Some breeders separate shrimplets to a dedicated raising tank for higher survival rates

Breeding Red Hinomaru shrimp can be rewarding, but it requires patience and attention to detail. Success often comes with experience and maintaining consistently excellent water quality. Remember that not all shrimplets will survive to adulthood, and it may take several generations of selective breeding to improve the quality of offspring.
