Caridina Orange Eye Purple Metallic Shrimp (Purple King Kong)

Caridina purple metallic shrimp are striking freshwater invertebrates known for their vibrant, iridescent purple coloration. These small crustaceans have an opaque body that shimmers with metallic hues, making them a popular choice among aquarium enthusiasts. They are accented by contrasting orange eyes. 

Scientific name and classification

The scientific name for these shrimp is Caridina cf. cantonensis. They belong to the genus Caridina within the family Atyidae. The “cf.” in the name stands for “confer,” indicating that while they are similar to Caridina cantonensis, their exact taxonomic status may require further study.

Origin and natural habitat

Caridina cf. cantonensis are native to Southeast Asia, particularly found in the freshwater streams and rivers of Taiwan. In their natural habitat, they prefer well-oxygenated waters with moderate flow and plenty of vegetation for grazing and shelter.

Physical appearance, size, and lifespan

These shrimp typically grow to a length of 2-3 cm (0.8-1.2 inches). The distinctive purple coloration is most prominent on their carapace and body and extends to their legs. This hue can vary in intensity depending on factors such as diet, water parameters, individual genetics, and even lighting.

Caridina purple metallic shrimp possess long, slender antennae and fan-like tails that aid in swimming and maneuvering through aquatic plants. Their small size is complemented by delicate legs adapted for grasping and foraging.

In optimal conditions, these shrimp can live for 2 years, depending on the quality of care they receive.

History of Caridina purple metallic shrimp

Development through selective breeding

Caridina purple metallic shrimp are a product of selective breeding programs, primarily developed in Taiwan. The process began with wild-type Caridina cantonensis, which naturally displays brown or clear coloration. Through careful selection of individuals with desirable traits and controlled breeding over multiple generations, aquaculturists gradually produced shrimp with increasingly vibrant and metallic purple hues.

This selective breeding process likely took several years, with breeders isolating and propagating shrimp that showed even the slightest purple coloration. Over time, they were able to stabilize the genetic traits responsible for the metallic purple appearance, resulting in the striking variety we see today.

Relation to Crystal Red Shrimp

Caridina purple metallic shrimp share a common ancestor with Crystal Red Shrimp (Caridina cantonensis var. “Crystal Red”). Both varieties originated from the same species, Caridina cantonensis. While Crystal Red Shrimp were selectively bred for their distinctive red and white coloration patterns, purple metallic shrimp were developed for their unique purple hues.

This shared lineage means that purple metallic shrimp have similar care requirements and breeding patterns to their Crystal Red cousins. However, the focus on different color traits has led to distinct appearances between the two varieties.

Popularity in the aquarium hobby

Since their introduction to the aquarium trade in the early 2010s, Caridina purple metallic shrimp have gained significant popularity among freshwater shrimp enthusiasts.

Larger tanks provide more stable water parameters and allow for a larger colony. The extra space also accommodates more plants and hiding places, creating a more natural and comfortable environment for the shrimp.

Filtration options

Sponge filters are the ideal choice for a Caridina purple metallic shrimp tank. These filters offer several advantages:

  1. Gentle flow: Shrimp prefer calm waters, and sponge filters provide adequate filtration without creating strong currents.
  2. Safety: The sponge material prevents shrimp, especially young ones, from being sucked into the filter.
  3. Biological filtration: Sponge filters offer an excellent surface area for beneficial bacteria to colonize.
  4. Food source: The sponge collects microorganisms that shrimp can graze on.

When selecting a sponge filter, ensure it’s appropriately sized for your tank. For larger setups, consider using multiple sponge filters to ensure proper water circulation and filtration.

Substrate choices

For Caridina purple metallic shrimp, using a pH-buffering soil substrate is crucial. Unlike substrates, these specialized soils help maintain the low pH and soft water conditions that these shrimp require. Popular options include:

  1. ADA Amazonia
  2. Fluval Stratum
  3. UNS Controsoil
  4. Brightwell Aquatics FlorinVolcanit

These substrates not only buffer the pH but also provide essential nutrients for plant growth. The dark color of these soils can also enhance the vibrant colors of the shrimp.

Importance of hiding places and plants

A well-planted tank with ample hiding spots is essential for Caridina purple metallic shrimp. These elements serve multiple purposes:

  1. Security: Shrimp feel safer with plenty of places to hide, reducing stress.
  2. Foraging areas: Plants and décor collect biofilm, a primary food source for shrimp.
  3. Molting shelter: Hidden areas provide safe spaces for vulnerable shrimp during molting.
  4. Water quality: Live plants help maintain water quality by absorbing nitrates.

Suitable plants include Java moss, Anubias, Cryptocoryne species, and floating plants like frogbit. Add driftwood, ceramic tubes, or shrimp-safe rocks to create additional hiding spots.

Acclimation process

Proper acclimation is crucial for the survival of Caridina purple metallic shrimp when introducing them to a new tank. Follow these steps:

  1. Float the bag: Let the sealed bag float in the tank for 15-20 minutes to equalize the temperature.
  2. Drip acclimation: Set up a drip system using airline tubing to slowly introduce tank water into the bag or a separate container holding the shrimp.
  3. Gradual adjustment: Allow the drip to continue for at least an hour, ideally achieving a 2-3x increase in water volume.
  4. Test parameters: Before transferring, ensure the water in the acclimation container matches the tank parameters.
  5. Transfer: Use a net to gently move the shrimp to the tank, avoiding transferring the shipping water.

Monitor the shrimp closely for the first few days after introduction, watching for signs of stress or unusual behavior.

Diet and Feeding

Natural feeding habits

In their natural habitat, Caridina purple metallic shrimp are primarily detritivores and algae eaters. They spend much of their time grazing on biofilm, algae, and decaying organic matter found on surfaces within their environment. Their specialized appendages allow them to efficiently scrape food particles from various surfaces.

Recommended commercial foods

While these shrimp will forage in a well-established aquarium, providing supplemental food ensures they receive a balanced diet. Recommended commercial foods include:

  1. Shrimp-specific pellets or granules (e.g., Glasgarten Shrimp Dinner, Dennerle Shrimp King Complete)
  2. Algae wafers
  3. Specialized shrimp foods rich in minerals for proper shell development
  4. High-quality fish flakes (in moderation)

Look for foods that are low in protein (around 30-35%) and free from copper additives, which can be harmful to shrimp.

Supplemental foods

To mimic their natural diet and provide variety, offer the following supplemental foods:

  1. Blanched vegetables: zucchini, spinach, kale, cucumber
  2. Leaf litter: Indian almond leaves, mulberry leaves, guava leaves
  3. Flowers: hibiscus, dandelion (pesticide-free)
  4. Specialized supplements: bee pollen, snowflake food (for extra minerals)
  5. Organic spirulina powder (sparingly)

These foods not only provide nutrition but also encourage natural foraging behaviors. Leaves and botanicals have the added benefit of releasing tannins, which can help maintain slightly acidic water conditions.

Feeding frequency and amount

Feed 2-3 times a week, an amount that the shrimp can consume within 1-2 hours. Avoid overfeeding to maintain water quality and prevent food from fouling the tank.

Remember that overfeeding can lead to poor water quality, which is detrimental to the shrimp. It’s better to underfeed slightly than to overfeed. The presence of biofilm and algae in the tank will provide a constant food source between feedings.

For breeding colonies or tanks with young shrimp, you may need to feed more frequently or provide finely powdered foods to ensure the smallest shrimp can access nutrition easily.

By providing a varied diet and following these feeding guidelines, you can help maintain the health, color, and vitality of your Caridina purple metallic shrimp.

I'm Stephanie, and I'm all about creating chill, low-maintenance underwater worlds. My aquascaping journey kicked off in college when I realized I could turn my fish tank into a mini slice of nature. I'm a huge fan of the Walstad method and basically anything that lets me be a bit lazy with my tanks while still keeping them looking awesome. Why fight nature when you can let it do its thing? Lately, I've been obsessed with figuring out how to make Caridina shrimp keeping less of a headache. Everyone's always going on about how finicky these little guys are, but I'm determined to prove that you can keep them happy without turning your life into a never-ending water change.
