Key Differences Between Caridina & Neocaridina, Every Shrimp Hobbyist Should Know
Caridina vs. Neocaridina: What’s the Difference?
For freshwater shrimp enthusiasts, Caridina and Neocaridina are two of the most popular genera of dwarf shrimp in the aquarium hobby. While they may look similar at first glance, these shrimp differ significantly in terms of water requirements, coloration, breeding habits, and tank setups. Understanding these differences can help hobbyists choose the right shrimp for their setup and ensure optimal care for these fascinating creatures.
1. Water Requirements
Caridina Shrimp:
pH: Acidic to neutral, ideally 6.0–7.0
Temperature: 68–74°F (20–23°C)
GH (General Hardness): 4–6 dGH
KH (Carbonate Hardness): 0–2 dKH
TDS (Total Dissolved Solids): 100–150 ppm
Caridina shrimp are more sensitive to water conditions and require soft, slightly acidic water. Their habitats are often found in slow-moving streams with stable parameters. Due to their sensitivity, they thrive best in environments with buffering substrates that help maintain low pH levels.
Neocaridina Shrimp:
pH: Neutral to slightly alkaline, ideally 6.5–7.5
Temperature: 68–78°F (20–25.5°C)
GH (General Hardness): 4–8 dGH
KH (Carbonate Hardness): 3–6 dKH
TDS (Total Dissolved Solids): 150–250 ppm
Neocaridina shrimp are more adaptable and forgiving of a wider range of water parameters. They can thrive in slightly harder water and are better suited for beginners due to their resilience.
2. Coloration
Caridina Shrimp:
Caridina shrimp, such as Crystal Red Shrimp (CRS) or Taiwan Bees, are known for their intricate and striking patterns. They often display bold colorations, including:
Red and white banded patterns (e.g., CRS)
Deep blues and blacks (e.g., Blue Bolt, Shadow Panda)
Unique tiger stripes and spot patterns (e.g., Tangerine Tigers)
Selective breeding has resulted in high-grade Caridina shrimp with stunning colors, but maintaining these vibrant colors requires precise water conditions and careful management.
Neocaridina Shrimp:
Neocaridina shrimp, such as Cherry Shrimp, are known for their solid and vibrant colors. Popular morphs include:
Red (e.g., Fire Red, Bloody Mary)
Blue (e.g., Blue Dream, Blue Velvet)
Yellow (e.g., Yellow Sakura)
Green, Orange, and even Chocolate varieties
Neocaridina shrimp are easier to breed for consistent colors, making them popular among hobbyists seeking a colorful tank without the added complexity of strict water requirements.
3. Breeding Habits
Caridina Shrimp:
Caridina shrimp are more challenging to breed due to their specific water requirements and higher sensitivity to changes. Successful breeding often involves:
Maintaining soft, acidic water
Providing a stress-free environment
Feeding a nutrient-rich diet to promote healthy eggs
Caridina shrimp typically lay fewer eggs (20–30 per cycle), and their fry are more sensitive, requiring pristine water conditions to thrive.
Neocaridina Shrimp:
Neocaridina shrimp are prolific breeders, even in less-than-perfect conditions. Key factors for successful breeding include:
Stable, moderately hard water
Abundant hiding spots for juveniles
A consistent food supply (biofilm, algae, and shrimp pellets)
Female Neocaridina shrimp can carry 20–50 eggs per cycle, and their fry are more robust, making them an excellent choice for beginner breeders.
4. Ideal Tank Setups
Caridina Shrimp:
Substrate: Active (buffering) substrate like ADA Amazonia to maintain low pH
Filtration: Sponge filters or low-flow filters to prevent stress
Decor: Driftwood, stones, and mosses for biofilm growth and hiding spots
Plants: Mosses like Java Moss and Bucephalandra to mimic natural habitats
Neocaridina Shrimp:
Substrate: Inert substrate like sand or gravel; no need for buffering properties
Filtration: Similar to Caridina, sponge filters work best
Decor: Similar setup with driftwood and mosses
Plants: Hardy plants like Anubias, Java Fern, and floating plants for shade
