Red Galaxy Caridina Shrimp – Freshwater Aquarium Shrimp

Red Galaxy Caridina Shrimp are beautiful ornamental freshwater dwarf shrimp known for their striking red-and-white coloration and intricate Galaxy-style markings. Their unique spotted patterns and contrasting colours make them a captivating addition to specialized shrimp aquariums and carefully maintained planted tanks.

Developed through selective breeding, Red Galaxy shrimp belong to the ornamental Caridina shrimp group and are especially popular among enthusiasts who appreciate distinctive patterns, vibrant coloration, and high-quality freshwater shrimp.

These shrimp spend much of their time exploring aquarium surfaces, grazing on biofilm and microorganisms, and moving through aquatic mosses and plants. They are best maintained in mature, stable aquariums with soft, slightly acidic water.

Key Features

• Beautiful Galaxy Markings: Distinctive spotted and patterned red-and-white coloration.
• Premium Ornamental Shrimp: Selectively bred for attractive colour and pattern characteristics.
• Peaceful Freshwater Invertebrate: Suitable for dedicated shrimp aquariums and carefully selected peaceful tankmates.
• Natural Grazing Behaviour: Constantly explores aquarium surfaces in search of biofilm and microorganisms.
• Excellent for Planted Aquariums: Particularly attractive alongside aquatic mosses, Bucephalandra, Anubias, and other freshwater plants.
• Compact Adult Size: Typically reaches approximately 2–3 cm.
• Breeds in Freshwater: Can reproduce in suitable, stable aquarium conditions.
• Unique Individual Patterns: Colour intensity, spotting, and markings naturally vary between shrimp.

Recommended Water Parameters

Red Galaxy Caridina Shrimp require more specialized water conditions than common Neocaridina shrimp. Maintaining consistent parameters is essential for successful long-term care.

These are general husbandry guidelines for bee-type Caridina shrimp. Actual optimal conditions may vary by breeding line and the parameters in which the shrimp were raised. Stability and gradual acclimation are especially important.

Ideal Aquarium Setup

Red Galaxy Caridina Shrimp perform best in mature aquariums with stable biological filtration and established biofilm. A dedicated shrimp aquarium is recommended, particularly for breeding or maintaining premium colour lines.

• Active Aquasoil: A buffering substrate helps maintain the acidic, low-KH conditions preferred by many Caridina shrimp.
• Remineralized RO Water: RO or RO/DI water remineralized with a suitable GH-only shrimp mineral product provides greater control over water chemistry.
• Gentle Filtration: Sponge filters or shrimp-safe intake guards help protect small shrimp and newborn shrimplets.
• Aquatic Mosses: Java Moss, Flame Moss, Willow Moss, and other mosses provide grazing surfaces and shelter.
• Stable Temperature: Avoid prolonged exposure to excessive heat and sudden temperature fluctuations.
• Mature Biological Filtration: Introduce shrimp only after the aquarium is fully cycled and water parameters have stabilized.

Feeding & Nutrition

Red Galaxy shrimp naturally graze on biofilm, algae, and microorganisms found throughout established aquariums. However, supplemental feeding is important for maintaining healthy shrimp.

A varied diet may include:

• High-quality Caridina shrimp food
• Biofilm-based shrimp foods
• Occasional protein-rich shrimp supplements
• Suitable botanical materials and leaf litter
• Mineral supplements when appropriate for the aquarium's water chemistry

Feed sparingly and remove uneaten food to prevent deterioration of water quality. Overfeeding can be particularly problematic in soft-water shrimp aquariums.

Acclimating Your Red Galaxy Shrimp

Because Caridina shrimp are sensitive to changes in water chemistry, careful acclimation is strongly recommended when introducing them to a new aquarium.

1. Prepare the Aquarium: Confirm that temperature, pH, GH, KH, and TDS are appropriate before introducing shrimp.
2. Inspect on Arrival: Check the shrimp and shipping water promptly upon delivery.
3. Drip Acclimate: Gradually introduce aquarium water using a controlled drip acclimation method, adjusting the duration according to differences in water parameters and shipping conditions.
4. Transfer Carefully: Gently move the shrimp into the aquarium without adding shipping water.
5. Reduce Stress: Keep aquarium lighting subdued and avoid unnecessary disturbances while the shrimp settle.

For shipped shrimp, prolonged exposure to opened shipping water may be harmful due to changes in ammonia toxicity. Follow the livestock acclimation guidance provided with your order and assess shipping conditions before beginning a lengthy drip acclimation.

Breeding Red Galaxy Caridina Shrimp

Under suitable conditions, Red Galaxy Caridina Shrimp can reproduce entirely in freshwater. Females carry fertilized eggs beneath their abdomen until the young hatch as miniature shrimp.

Successful breeding generally requires stable water chemistry, appropriate nutrition, gentle filtration, and a mature aquarium with abundant biofilm.

Because Galaxy shrimp are selectively bred for their patterns, offspring may display variations in colour intensity, spotting, and markings. Maintaining consistent appearance across generations may require selective breeding.

Live Shrimp Shipping Information

Red Galaxy Caridina Shrimp are live aquatic animals and require careful handling during shipping. We strongly recommend Express Shipping to minimize transit time and reduce stress.

Live shrimp should be introduced to a fully established aquarium with suitable water conditions. Please review our live arrival guarantee and acclimation recommendations before ordering.

Each shrimp is unique. Colour, size, pattern, and spotting may vary naturally. Product photographs are representative of the variety and do not guarantee identical markings on every individual.
