About Carbon Rili Shrimp
Carbon Rili Shrimp hold a special place in Neocaridina history as the genetic foundation from which Blue Dream Shrimp were developed. Their distinctive appearance features near-black or charcoal coloring on the head and tail sections, separated by a crystal-clear transparent midsection. This dramatic contrast creates a striking 'tuxedo' effect that makes them stand out in any aquarium. The development of Carbon Rili from Red Rili Shrimp was a crucial stepping stone in creating blue Neocaridina varieties. Breeders selecting for darker coloration eventually produced individuals with blue undertones, and continued selection led to the creation of Blue Dream Shrimp - one of the most popular blue varieties today. Understanding this lineage helps explain the genetic connections between many modern Neocaridina varieties. Carbon Rili Shrimp remain popular in their own right for their sophisticated, dramatic appearance. The deep, almost black coloring combined with the transparent midsection creates an elegant look that appeals to hobbyists seeking something different from the typical bright colors. They're sometimes called 'Blue Carbon Rili' when they display noticeable blue undertones in their dark coloring, though this varies by individual and line.
Quick Facts
Water Parameters for Carbon Rili Shrimp
Maintaining stable water parameters is crucial for the health and coloration of Carbon Rili Shrimp. As a Neocaridina species, they are relatively hardy and can tolerate a wider range of parameters than Caridina species.
| Parameter | Range | Optimal |
|---|---|---|
| TDS | 150-300 ppm | 180-250 ppm |
| GH | 4-14 dGH | 6-8 dGH |
| KH | 2-8 dKH | 2-5 dKH |
| pH | 6.5-8 | 6.8-7.5 |
| Temperature | 64-82°F (18-28°C) | 68-75°F |
Tank Setup for Carbon Rili Shrimp
- Minimum 5 gallon tank recommended
- Light or white substrate creates striking contrast
- Dense planting provides security and grazing surfaces
- Good lighting showcases their dramatic coloring
- Sponge filter is ideal for shrimp safety
Care Tips for Carbon Rili Shrimp
- Keep in groups of at least 10 for natural behavior
- Maintain stable water parameters - standard Neocaridina requirements
- Provide plenty of plants and hiding spots
- Light substrate creates dramatic contrast with dark extremities
- Their transparent midsection makes health monitoring easy
- Avoid copper-based medications
- Small weekly water changes of 10-15% are recommended
Feeding Carbon Rili Shrimp
- Feed high-quality shrimp foods 2-3 times weekly
- Biofilm is essential and should be primary food source
- Varied diet helps maintain good coloration
- Blanched vegetables provide excellent nutrition
- Transparent middle lets you observe feeding behavior
Breeding Carbon Rili Shrimp
- Genetic ancestor of Blue Dream Shrimp
- May produce offspring with blue undertones or full blue coloring
- Pattern expression varies - some offspring may be more solid
- Blue undertones can be selected for over generations
- Keep separate from other colors to maintain Carbon line
Carbon Rili Shrimp Grading System
Carbon Rili Shrimp are commonly graded based on color intensity, coverage, and pattern quality. Higher grades typically command higher prices and are the result of selective breeding.
Standard Carbon Rili
Clear midsection with medium gray to dark coloring on head and tail.
Characteristics
- Clear transparent middle
- Dark gray extremities
- Visible Rili pattern
- Color intensity varies
High Grade Carbon Rili
Crystal clear midsection with deep, near-black coloring on head and tail.
Characteristics
- Very clear transparent middle
- Near-black extremities
- Sharp color boundaries
- Blue undertones possible
Grades listed from lowest to highest quality
Common Problems with Carbon Rili Shrimp
- Pattern expression varies among offspring
- May produce Blue Dream-like offspring when blue genes express
- Dark coloring can make them harder to see on dark substrates
- Blue undertones not always consistent across colony
- Genetics can be complex when tracing Blue Dream ancestry

Carbon Rili Shrimp FAQ
Carbon Rili Shrimp are the direct ancestors of Blue Dream Shrimp. Breeders selected Carbon Rili with blue undertones and, over generations, developed the solid blue coloration of Blue Dream Shrimp. This makes Carbon Rili historically significant in Neocaridina breeding history.
Carbon Rili have the classic Rili pattern - dark head and tail with clear midsection. Black Rose Shrimp are solid dark/black throughout without the transparent section. They also come from different genetic lines (Carbon Rili from Red Rili, Black Rose from Chocolate).
Carbon Rili can carry genes for blue coloration - this is actually how Blue Dream Shrimp were developed. Individuals with stronger blue undertones are sometimes called Blue Carbon Rili. This blue expression varies by individual and genetic line.
Theoretically yes, since Blue Dream originated from Carbon Rili. However, it took many generations of selective breeding. Your Carbon Rili may produce offspring with increased blue expression, but creating true Blue Dream requires dedicated selective breeding over time.
Absolutely! They have the same hardy, easy-care requirements as all Neocaridina. They're no more difficult than Cherry Shrimp - just with a different, more dramatic appearance.
Light or white substrate creates the most dramatic visual contrast, making their dark extremities and clear midsection really stand out. On dark substrate, they can be harder to see and the effect is less striking.
Carbon Rili carry complex genetics including potential for blue expression and varying pattern intensity. Offspring can range from dark Carbon Rili to more blue-toned individuals to varying pattern expressions. This genetic diversity is normal for this variety.
