Black Rili Shrimp

Appearance:

• Size: Adult Black Rili Shrimp grow to about 1-1.5 inches (2.5-3.8 cm), like other Neocaridina species.
• Coloration: Black Rili Shrimp have a unique black-and-transparent color pattern. The black portions usually cover the head and tail, while the middle of the shrimp is often transparent or translucent. This striking contrast makes them stand out in any tank.
• Variation: Depending on the genetics and grade of the shrimp, the intensity and distribution of the black coloration may vary. Higher-grade Black Rili Shrimp have more defined and uniform black patches with clearer transparent areas.

Natural Habitat:

• Origin: Like other Neocaridina species, Black Rili Shrimp originate from freshwater streams and ponds in Taiwan. However, the Black Rili variant is a selectively bred color morph developed in captivity.
• Environment: In their natural habitat, they thrive in areas with dense plant growth, rocks, and debris, where they can find plenty of biofilm and organic matter to feed on.

Water Conditions:

• Temperature: They are quite adaptable, thriving in a temperature range of 65-80°F (18-27°C). For optimal health and breeding, maintain the temperature between 72-78°F (22-26°C).
• pH: Black Rili Shrimp prefer slightly alkaline to neutral water with a pH of 6.5-8.0.
• Water Hardness: They prefer moderate to hard water with a general hardness (GH) of 6-8 and a carbonate hardness (KH) of 3-6.
• Water Quality: As with all shrimp, maintaining stable, clean water is important. Regular water changes and a well-cycled tank with no traces of ammonia or nitrite are crucial. Nitrates should also be kept below 20 ppm for the best health.

Tank Setup:

• Tank Size: A minimum of 5 gallons is recommended for a small group of Black Rili Shrimp, though a larger tank (10 gallons or more) is better for long-term success and colony growth.
• Substrate: Inert substrates like gravel or sand work well, as Black Rili Shrimp are not particularly sensitive to substrate type. They will forage on the tank floor for food, so a darker substrate can enhance their colors.
• Plants & Decorations: Live plants, driftwood, and rocks are ideal for providing hiding spaces and surfaces for biofilm to grow. Java Moss, Anubias, and other low-light plants are excellent choices for a shrimp tank. Plants also help improve water quality and provide extra surfaces for the shrimp to graze on.
• Filtration: Sponge filters are highly recommended for shrimp tanks, as they provide gentle filtration and create a biofilm on their surface that shrimp love to graze on.
• Lighting: Moderate lighting is sufficient, especially if you have live plants.

Behavior:

• Peaceful: Black Rili Shrimp are non-aggressive and highly peaceful, spending most of their time grazing on biofilm, algae, and detritus in the tank.
• Active Grazers: These shrimp are highly active and can often be seen scavenging and foraging throughout the day.
• Social Creatures: They are best kept in groups of 10 or more, which helps reduce stress and encourages natural behavior. Larger groups also lead to healthier, more stable colonies.

Tank Mates:

• Ideal Tank Mates: Black Rili Shrimp can be kept with other peaceful shrimp species, like Red Cherry Shrimp or Amano Shrimp, as well as non-aggressive fish such as small rasboras, tetras, or Otocinclus. Snails, like Nerite snails, also make good companions.
• Avoid Predators: Avoid housing them with aggressive or predatory fish, such as cichlids or large species that may see them as food.
• Shrimp-Only Tanks: Many hobbyists prefer to keep Black Rili Shrimp in species-only tanks or shrimp-specific tanks to ensure the best conditions for breeding and colony growth.

Feeding:

• Omnivores: Black Rili Shrimp are omnivores and primarily feed on biofilm, algae, and decaying plant matter.
• Diet: In addition to natural grazing, supplement their diet with high-quality shrimp pellets, algae wafers, blanched vegetables (like spinach, zucchini, or kale), and occasional protein sources like bloodworms or brine shrimp. Make sure not to overfeed, as leftover food can affect water quality.
• Algae Control: While they will graze on algae, they are not as efficient at algae control as other species like Amano Shrimp.

Breeding:

• Ease of Breeding: Like other Neocaridina species, Black Rili Shrimp are prolific breeders and will readily breed in well-maintained tanks with stable water conditions.
• Breeding Conditions: Females will carry eggs under their abdomen for about 3-4 weeks. These eggs hatch into miniature versions of the adults that do not have a larval stage.
• Selective Breeding: If you're interested in enhancing the color patterns of your shrimp, selective breeding can help increase the intensity and clarity of the black-and-transparent coloration in future generations.
• No Special Setup Required: No special breeding setup is needed, as long as the water conditions are good and there are plenty of hiding places for the shrimp to feel secure.

Lifespan:

• Lifespan: Black Rili Shrimp typically live for 1-2 years, but with excellent care, they may live slightly longer.

Special Considerations:

• Copper Sensitivity: Like all shrimp, Black Rili Shrimp are highly sensitive to copper. Avoid using medications or fertilizers that contain copper in their tank, as even small amounts can be lethal.
• Acclimation: When introducing Black Rili Shrimp to a new tank, it's important to use a slow drip acclimation process to prevent shock from sudden changes in water parameters.
• Water Changes: Regular water changes of 10-20% weekly are important to maintain water quality, but make sure to use dechlorinated water and avoid large fluctuations in temperature or pH.
