Jet Black Shrimp | Adult-Single

Jet Black Shrimp (Caridina cf. cantonensis), also known as Black Tiger Shrimp, are a striking species of freshwater shrimp known for their deep black coloration. They are highly sought after in the aquarium hobby for their unique appearance and ability to add dramatic contrast to aquascapes, especially in tanks with light-colored or green plants. Like other species of freshwater shrimp, Jet Black Shrimp also help in maintaining the tank’s cleanliness by consuming algae, detritus, and leftover food.
Key Characteristics of Jet Black Shrimp:
Size: Typically reach 2-3 cm (0.8–1.2 inches) in length.
Color: The defining characteristic of Jet Black Shrimp is their deep, glossy black color, which can sometimes have darker or lighter variations depending on their genetics and environmental factors.
Lifespan: Usually live around 1–2 years, with proper care.
Temperament: Peaceful and non-aggressive, they are ideal for community tanks with other small, non-aggressive fish and shrimp.
Behavior: Active and social, often found grazing on surfaces, substrate, and plants in search of algae or biofilm.
Water Parameters for Jet Black Shrimp:
Temperature: 20–28°C (68–82°F). They prefer warmer water and should be kept in a stable temperature range.
pH: 6.5–7.5. They thrive in slightly acidic to neutral water, although they are somewhat adaptable to different pH levels.
Hardness: 4–8 dGH (degrees of general hardness). Softer water is generally preferred for breeding, but they can tolerate a wider range of hardness.
Ammonia & Nitrite Levels: Must always be 0 ppm. Jet Black Shrimp are sensitive to water quality issues, particularly ammonia and nitrites.
Nitrate Levels: Keep nitrates under 20 ppm for optimal health.
Aquarium Setup:
Tank Size: A minimum of 10-20 gallons is ideal. However, they can be kept in smaller tanks as long as water conditions are kept stable.
Substrate: Fine gravel, sand, or a nutrient-rich substrate works well. Avoid sharp-edged substrates that may injure the shrimp.
Filtration: A sponge filter or a gentle power filter is preferred to maintain a low water flow, as strong currents can stress the shrimp.
Plants & Decor: Jet Black Shrimp prefer a well-planted tank with lots of hiding spots. Live plants such as java moss, anubias, and cryptocoryne provide both aesthetic value and security for the shrimp. Driftwood and rocks also serve as excellent hiding places.
Lighting: Moderate lighting is ideal. Too much light can lead to algae growth, which may disrupt the shrimp’s natural grazing behavior.
Diet:
Algae: Jet Black Shrimp naturally graze on algae that grows on plants, rocks, and tank surfaces. They are efficient at keeping algae under control.
Shrimp Pellets: High-quality shrimp pellets or granules provide essential nutrients for their growth and health.
Vegetables: Blanched vegetables such as zucchini, spinach, or cucumber are excellent occasional treats.
Biofilm: As scavengers, they feed on biofilm (a thin layer of organic material) that forms on surfaces in the aquarium.
Supplementary Foods: You can also feed them spirulina-based flakes or other specialized shrimp food to ensure they get a balanced diet.
Breeding Jet Black Shrimp:
Breeding Behavior: Jet Black Shrimp breed readily in stable, well-maintained tanks. Females carry eggs under their tails (berried) and will hatch into miniature versions of adult shrimp.
Water Conditions for Breeding: To encourage breeding, maintain stable water conditions. Softer, slightly acidic water (pH 6.5–7.0) can stimulate reproduction.
Fry Care: The young shrimp, known as "fry," are born fully formed and will immediately begin foraging for algae and biofilm. They are tiny and will need plenty of hiding places to avoid being eaten by larger fish or more aggressive tankmates.
Molting: As with other shrimp species, Jet Black Shrimp will molt as they grow, shedding their exoskeleton and growing a new one. Providing plenty of calcium and minerals in the water can help them molt successfully.
Tankmates for Jet Black Shrimp:
Suitable Tankmates:
Small, peaceful fish such as neon tetras, guppies, or rasboras.
Other shrimp species such as Crystal Red Shrimp, Amano Shrimp, or other Neocaridina species.
Small snails like Nerite or Mystery snails.
Avoid Tankmates:
Large or aggressive fish (like cichlids or predatory species) can pose a threat to the shrimp.
Bigger shrimp species that might compete for food or harm the Jet Black Shrimp.
Benefits of Jet Black Shrimp in the Aquarium:
Algae Control: Jet Black Shrimp are excellent at grazing on algae and detritus, keeping your aquarium clean without the need for additional cleaning equipment.
Aesthetic Appeal: Their deep black coloration provides a striking contrast in planted tanks and adds visual interest, especially when they move among vibrant green plants.
Natural Behavior: Watching the shrimp’s active behavior and interactions with their environment adds life and dynamism to your aquarium.
Water Quality: By eating organic waste, they help maintain good water quality and reduce the risk of algae blooms.
Conclusion:
Jet Black Shrimp are an outstanding choice for aquarists looking to add color and movement to their tank while also promoting a healthy, balanced ecosystem. Their low maintenance, peaceful nature, and algae-eating habits make them excellent additions to both beginner and advanced aquariums. With stable water conditions, proper diet, and appropriate tankmates, these beautiful shrimp will thrive and enhance your aquarium for years to come.
