Bloody Mary Shrimp

Species Profile

• Scientific Name: Neocaridina species
• Common Name: Bloody Mary Shrimp
• Adult Size: 1–1.5 inches (2.5–3.8 cm)
• Life Expectancy: 1–2 years, though some may live up to 2.5 years with optimal care
• Habitat:
  • Originates from freshwater streams and ponds in East and Southeast Asia

  • Prefers densely planted, calm, and clean aquatic environments

Tank Requirements

• Minimum Tank Size: 5–10 gallons for a small colony
  (Larger tanks are more stable and recommended for breeding)
• Ideal Temperature: 68–78°F (20–25.5°C)
• pH Range: 6.5–7.5
• Water Hardness: 4–12 dGH (moderately soft to slightly hard water)

• Temperament: Peaceful and social
  Best kept in groups
  Safe with small, non-aggressive tank mates or in species-only tanks

Diet & Nutrition

• Omnivorous scavengers
• Will eat:
  • Biofilm
  • Algae
  • Blanched vegetables (zucchini, spinach)
  • Shrimp pellets
  • Fish food flakes

• Important to avoid copper in foods, as it's toxic to shrimp

Breeding & Spawning

• Easy to breed in freshwater if water conditions are stable
• Females carry eggs under their tail (called "berried")
• Eggs hatch into miniature shrimplets (no larval stage)

• Provide plenty of hiding spaces with plants or moss for baby shrimp survival

Appearance

• Bright emerald green coloration across the body
• Semi-transparent or opaque depending on genetics and environment

• Slender body with five pairs of walking legs and fan-like tail

Distinctive Features

• Eye-catching green color due to selective breeding
• Active during the day, often seen grazing on surfaces
• Excellent algae cleaners and tank scavengers

• Color intensity can be influenced by diet, tank conditions, and substrate
