Bloody Mary Neocaridina (Low-mid Grade)

Bloody Mary Shrimp are one of the most popular freshwater shrimp varieties in the aquarium hobby. Known for their rich red coloration and active behaviour, they make a beautiful and useful addition to planted aquariums and shrimp tanks.

This listing is for low–mid grade Bloody Mary shrimp, which may show lighter red coloration or more transparent areas compared to high-grade specimens, but are still healthy and excellent for aquariums or breeding colonies.

These shrimp are perfect for aquarists looking to start a shrimp colony or add colour and activity to their tank at a more affordable price.

At N8 Aquatics, our shrimp are raised in stable aquarium environments to ensure healthy livestock ready for your aquarium.

Why Keep Neocaridina Shrimp

Bloody Mary shrimp are popular because they:

• help clean algae and biofilm
• are peaceful and community-friendly
• breed readily in aquariums
• add constant activity to planted tanks
• bring natural colour to aquascapes

They are one of the best shrimp species for beginners and experienced aquarists alike.

Grade Explanation

Low–mid grade shrimp may show:

• lighter red coloration
• transparent patches
• uneven colour coverage

These shrimp are still healthy and fully capable of breeding, making them ideal for starting a shrimp colony or for community aquariums.

Higher-grade shrimp are typically sold separately due to their deeper colour and stronger genetic traits.

Diet

Bloody Mary shrimp will graze naturally in the aquarium but benefit from supplemental feeding.

Recommended foods include:

• shrimp pellets
• algae wafers
• blanched vegetables
• biofilm and algae
• powdered shrimp foods

Avoid overfeeding as shrimp require very small amounts of food.

Compatibility

Bloody Mary shrimp are peaceful and best kept with other gentle species.

Suitable tankmates include:

• small peaceful fish
• nano fish
• snails
• other Neocaridina shrimp

Avoid fish that may prey on shrimp.

Behaviour

Bloody Mary shrimp are constantly active, grazing on surfaces and exploring the aquarium.

When kept in colonies they display natural behaviour including:

• grazing on biofilm

Well-maintained shrimp tanks can quickly develop thriving colonies.
