Bloody Mary Shrimp

Introduction

The Bloody Mary Shrimp is a popular and striking freshwater shrimp known for its vibrant red coloration. With its deep red hue and small, hardy nature, this shrimp makes a fantastic addition to planted aquariums. It is a peaceful species, ideal for community tanks, and its maintenance is relatively straightforward, making it a great choice for both beginners and experienced aquarists. Bloody Mary Shrimp are not only visually captivating but also serve as natural cleaners by grazing on algae and detritus in the aquarium.

Scientific Name

Neocaridina davidi

Common Name

• Bloody Mary Shrimp

• Red Cherry Shrimp (similar but different from the Red Cherry Shrimp species)

Water Quality and Temperature

To ensure the health of Bloody Mary Shrimp, it’s important to maintain water conditions similar to their natural habitat.

• Temperature: 65°F – 75°F (18°C – 24°C)

• pH Level: 6.5 – 8.0 (slightly acidic to neutral)

• Hardness: 4 – 8 dKH

• Ammonia/Nitrite Levels: Should be zero; maintain low nitrate levels

• Filtration: Low to moderate filtration is preferred, but strong currents should be avoided.

Feeding

The Bloody Mary Shrimp is an omnivorous scavenger that enjoys a varied diet. In the wild, they feed on algae, biofilm, and detritus, but in aquariums, you can provide a more controlled diet.

• Preferred Diet:

  • High-quality shrimp flakes or pellets

  • Algae wafers

  • Blanched vegetables (spinach, zucchini, etc.)

  • Occasional protein-rich foods (like daphnia or brine shrimp)

• Feeding Frequency: Feed small portions 2-3 times per week, but be careful not to overfeed as this can lead to water quality issues.

Tank Mates

Bloody Mary Shrimp are peaceful and should be housed with other non-aggressive species. They can be kept in community tanks with a variety of other peaceful fish and invertebrates.

• Compatible Tank Mates:

  • Peaceful small fish like neon tetras, guppies, and rasboras

  • Snails (such as Nerite snails)

  • Other freshwater shrimp species (as long as they aren’t aggressive)

• Avoid:

  • Larger or aggressive fish like cichlids, bettas, and goldfish, which may eat the shrimp.

  • Larger, fast-moving fish that might outcompete them for food.

Substrates and Tank Decorations

Bloody Mary Shrimp thrive in tanks with a well-planted setup, providing both hiding spaces and areas to forage.

• Substrate: Fine gravel, sand, or nutrient-rich soil, especially if live plants are present, as shrimp like to forage through the substrate.

• Tank Decor:

  • Driftwood and rocks to provide hiding places

  • Live plants such as java moss, Anubias, and Java fern, which give the shrimp plenty of surface area for grazing.

  • Moss or algae-covered surfaces will also be appreciated, as they provide a natural food source.

Suitable Plants

Live plants are not only aesthetically pleasing but also provide grazing surfaces for the shrimp.

• Java moss
• Cryptocoryne
• Java fern
• Hornwort
• Anubias

Sexing

Male and female Bloody Mary Shrimp can be distinguished by their size and coloration.

• Male: Males are smaller and typically more transparent, often displaying a lighter red or brownish tint.

• Female: Females are larger and have a more intense, vibrant red color. They may also have a visible “saddle” of eggs in their abdomen when they are carrying eggs.

Breeding

Breeding Bloody Mary Shrimp in captivity is relatively easy, and once established, they will breed readily.

• Breeding Behavior:

  • Females will carry eggs under their tail (saddle), where they develop into larvae.

  • After hatching, the larvae will settle to the substrate and begin their juvenile stage, developing into fully formed shrimplets.

  • If kept in a well-maintained tank with good water quality, Bloody Mary Shrimp will reproduce on their own.

• Fry Care:

  • The baby shrimp will require algae, biofilm, and crushed shrimp food to grow. It’s important to avoid any predatory tank mates that could eat the shrimplets.

Maximum Size and Longevity

• Size: Up to 1.5 inches (4 cm)

• Lifespan: 1.5 – 2 years, with proper care and stable water conditions.

General Information

Bloody Mary Shrimp are small, active, and colorful creatures that make an excellent addition to any freshwater aquarium. They are known for their ability to keep tanks clean by eating algae and leftover food. As a peaceful species, they are a joy to watch and relatively easy to care for, making them a popular choice among shrimp enthusiasts.

A Fun Fact

The vibrant red coloration of the Bloody Mary Shrimp is a result of selective breeding. This shrimp is a variant of the Red Cherry Shrimp, but it has been bred for its rich, dark red appearance. The deeper color is more prominent in males and females that are well-fed and kept in optimal water conditions.
