The Captivating World of Blue Dream Shrimp: A Comprehensive Guide

Introduction

The vibrant and elusive blue dream shrimp (Neocaridina davidi var. Blue Dream), a prized possession in the ornamental shrimp hobby, has captured the hearts of aquarists worldwide. With its iridescent blue hue and intricate patterns, the blue dream shrimp adds an enchanting touch to any aquarium. This comprehensive guide will unveil the fascinating world of blue dream shrimp, providing indispensable knowledge for their successful care and breeding.

Taxonomy and Origins

The blue dream shrimp is a member of the family Atyidae, belonging to the genus Neocaridina. Native to southern China, the species was initially discovered in the Li River basin. Blue dream shrimp, a color morph of the neocaridina shrimp, were selectively bred in Japan to achieve their captivating blue coloration.

Physical Characteristics

• Size: Average length of 1.5-2.5 cm (0.6-1 in)
• Coloration: Electric blue body with translucent legs and antennae, often adorned with faint brown or black stripes
• Lifespan: 1-2 years in captivity

Optimal Water Parameters

Creating a thriving environment for blue dream shrimp is crucial for their well-being. Ideal water parameters include:

• Temperature: 22-26°C (72-79°F)
• pH: 6.5-8.0
• Hardness (GH): 4-8 dGH
• Carbonate Hardness (KH): 2-4 dKH
• Ammonia and Nitrite: 0 ppm
• Nitrate: Below 10 ppm

Habitat Requirements

Blue dream shrimp prefer densely planted aquariums with plenty of hiding places, such as live aquatic plants, driftwood, and rocks. They thrive on a diet of algae, biofilm, and supplemental foods like blanched vegetables, shrimp pellets, and flake food.

Behavior

Blue dream shrimp are generally peaceful and social creatures, coexisting harmoniously in groups. However, they may exhibit territorial behaviors towards other shrimp species. They spend their days scavenging for food and grazing on algae.

Reproduction

Breeding blue dream shrimp requires dedicated knowledge and attention to detail. Females carry their eggs externally, attached to their pleopods, for approximately 30 days. Hatchling shrimp, known as "shrimplets," are tiny and require specialized care to reach maturity.

Interesting Stories

1. The Helpful Hitchhiker: A group of blue dream shrimp found themselves in an aquarium with a territorial betta fish. While the shrimp initially hid from the betta, they soon discovered that the fish's presence helped deter other predators, creating an unexpected symbiotic relationship.
2. The Blue Misidentification: An aquarist purchased a group of blue dream shrimp, only to realize later that they were actually cobalt dream shrimp, a different color morph of Neocaridina davidi. Despite the mix-up, the aquarist appreciated the stunning blue coloration of his new shrimp.
3. The Shrimpy Escape: A blue dream shrimp found a small hole in the aquarium lid and made a daring escape into the greater world of the house. While it was eventually retrieved and returned to the tank, the incident reminded the owner to secure the aquarium properly.

FAQs

1. What is the average lifespan of a blue dream shrimp?

Answer: In captivity, blue dream shrimp typically live for 1-2 years.

2. Can blue dream shrimp live with other shrimp species?

Answer: Generally, yes. Blue dream shrimp are peaceful and can coexist with other Neocaridina species. However, it is essential to monitor their interactions closely, especially during breeding.

3. How often should I feed my blue dream shrimp?

Answer: Blue dream shrimp should be fed small amounts of food daily or every other day. Provide algae, biofilm, and supplemental foods like blanched vegetables, shrimp pellets, or flake food.

4. What is the difference between blue dream shrimp and cobalt dream shrimp?

Answer: Both blue dream shrimp and cobalt dream shrimp are color morphs of Neocaridina davidi. Cobalt dream shrimp have a deeper, more saturated blue coloration, while blue dream shrimp exhibit a more electric blue hue.

5. Why are my blue dream shrimp turning brown?

Answer: Stress or a lack of minerals, such as calcium or magnesium, can cause blue dream shrimp to turn brown. Ensure optimal water parameters and provide a balanced diet to prevent this discoloration.

6. Can I breed blue dream shrimp with red cherry shrimp?

Answer: Yes, it is possible to breed blue dream shrimp with red cherry shrimp. The resulting offspring will be known as a blue or red rili shrimp, displaying a mix of blue and red coloration.

7. What is the best way to acclimate blue dream shrimp to a new aquarium?

Answer: Float the bag of shrimp in the aquarium water for at least 30 minutes to gradually equalize the temperature and water conditions. Gradually add tank water to the bag until it is completely full before releasing the shrimp into the aquarium.

8. Can blue dream shrimp eat fish food?

Answer: Yes, blue dream shrimp can eat fish food as a supplemental treat. However, it is important to avoid overfeeding and provide a varied diet to ensure a healthy balance.
