Yellow Neocaridina Shrimp
Neocaridina davidi
📍 Taiwan
Yellow Neocaridina shrimp are vibrant, hardy freshwater shrimp that display a bright yellow coloration, making them popular for planted and community aquariums. These peaceful invertebrates are excellent algae grazers and detritivores, helping maintain tank cleanliness while adding visual interest. They are ideal for beginners due to their resilience and ease of care.
Care Guide
Diet
Yellow Neocaridina are primarily detritivores that thrive on biofilm, algae, and decaying plant matter in established tanks. Supplement with high-quality shrimp pellets, algae wafers, and blanched vegetables (spinach, zucchini, carrot) 2-3 times weekly. A mature, well-planted tank with adequate biofilm is essential for their long-term health.
Behavior
These shrimp are active foragers that spend most of their time on the substrate and plants searching for food. They are social animals that do best in groups and exhibit minimal aggression toward tank mates. Yellow Neocaridina molt regularly as they grow; provide plenty of hiding spots with plants and hardscape to help them feel secure during vulnerable molting periods.
Breeding
Yellow Neocaridina breed readily in freshwater without requiring brackish conditions, making them excellent for home aquariums. Females produce small batches of 20-30 shrimplets every few weeks under good conditions. Provide dense vegetation and stable water parameters to maximize survival rates of juveniles.
Tank Mates
Similar peaceful nature and compatible water parameters; excellent algae-eating companions
Peaceful, similar size and care requirements; can cohabitate without aggression
Small, peaceful fish that will not prey on adult shrimp; avoid with shrimplets
Peaceful algae eater with compatible water parameters and feeding habits
Generally peaceful; monitor for aggression toward shrimp, especially during breeding
Common Diseases
Molting Stress / Failed Molt
Shrimp stuck in old exoskeleton, lethargy, inability to move freely, death if unable to escape
Ensure adequate calcium and minerals through quality shrimp food and mineral supplements; maintain stable water parameters; provide hiding spots; do not disturb molting shrimp
Copper Toxicity
Lethargy, loss of appetite, discoloration, sudden death
Avoid all copper-based medications and fertilizers; use only shrimp-safe products; perform water changes if copper contamination is suspected; use activated carbon in filter
Bacterial Infection / Shell Erosion
White spots on body, cloudy appearance, shell pitting or erosion, lethargy
Improve water quality through frequent water changes; increase aeration; remove affected individuals to quarantine; maintain pH above 6.5 to support shell integrity
Parasitic Infection (Flukes)
Excessive scratching on plants/hardscape, rapid gill movement, lethargy, loss of appetite
Perform 25-30% water changes every 2-3 days; increase water flow and aeration; use shrimp-safe parasite treatments; avoid copper-based medications; quarantine affected shrimp if possible
