Pure Red Line Crystal Shrimp

Pure Red Line (PRL) Crystal Shrimp are a highly sought-after and visually stunning variety of freshwater dwarf shrimp, specifically a selectively bred strain of **Caridina cantonensis**. They are known for their striking red and white coloration and are a favorite among advanced shrimp keepers. Here’s a detailed description:

---

### **Appearance:**

- **Color Pattern**: PRL Crystal Shrimp have a bold, high-contrast pattern of **pure white** and **vivid red** bands. The red is deep and opaque, while the white is clean and bright.

- **Body**: Their body is divided into distinct sections of red and white, often with a solid white head and tail, and red bands in the middle.

- **Size**: They are small, typically growing to about 1-1.5 inches (2.5-4 cm) in length.

- **Transparency**: Unlike some other shrimp, PRL Crystal Shrimp have a solid, opaque appearance with no transparency.

---

### **Behavior:**

- **Peaceful**: Like most dwarf shrimp, they are non-aggressive and thrive in peaceful community tanks.

- **Active Foragers**: They spend much of their time grazing on biofilm, algae, and detritus.

- **Sensitive**: They are more delicate than Neocaridina species (like Red Cherry Shrimp) and require stable water conditions.

---

### **Habitat and Care:**

- **Water Parameters**: PRL Crystal Shrimp are more demanding than Neocaridina species. They require:

  - **pH**: 5.8-6.8 (slightly acidic).

  - **Temperature**: 68-78°F (20-25°C).

  - **GH (General Hardness)**: 4-6 dGH.

  - **KH (Carbonate Hardness)**: 0-2 dKH.

  - **TDS (Total Dissolved Solids)**: 100-150 ppm.

- **Tank Setup**: They thrive in planted tanks with plenty of hiding spots, such as moss (e.g., Java Moss), driftwood, and rocks. A dark substrate (e.g., ADA Aqua Soil) enhances their colors.

- **Water Quality**: They are sensitive to ammonia, nitrites, and nitrates, so regular water changes and a well-cycled tank are essential.

---

### **Diet:**

- **Omnivorous**: They feed on biofilm, algae, and specialized shrimp foods. Supplement their diet with:

  - Blanched vegetables (e.g., spinach, zucchini).

  - High-quality shrimp pellets or mineral supplements.

  - Bacter AE (to promote biofilm growth).

---

### **Breeding:**

- **Selective Breeding**: PRL Crystal Shrimp are the result of careful selective breeding to achieve their pure red and white coloration.

- **Breeding Difficulty**: They are moderately difficult to breed due to their specific water parameter requirements.

- **Eggs**: Females carry 20-30 eggs under their tails for about 3-4 weeks until they hatch.

- **Fry Care**: The baby shrimp are miniature versions of adults and require the same water conditions. They benefit from fine-leaved plants or moss for hiding and feeding.

---

### **Grades:**

PRL Crystal Shrimp are graded based on the intensity and coverage of their red and white coloration:

- **SS Grade**: The highest grade, with solid, opaque white and deep red bands, and no visible flaws.

- **S Grade**: Slightly less intense coloration but still high-quality.

- **A Grade**: Less coverage of red and white, with some transparency or uneven patterns.

---

### **Compatibility:**

- **Tank Mates**: They should be kept with other small, peaceful species like other Caridina shrimp (e.g., Tiger Shrimp) or snails. Avoid fish, as they may prey on the shrimp or their fry.

- **Species-Only Tanks**: Many keepers prefer to house PRL Crystal Shrimp in species-only tanks to maintain water quality and prevent crossbreeding.

---

### **Challenges:**

- **Water Stability**: They are sensitive to fluctuations in water parameters, so maintaining stability is crucial.

- **Crossbreeding**: If kept with other Caridina species, they may hybridize, diluting the pure red line genetics.
