Crystal Shrimp (Pure Red Line)

The Crystal Red Shrimp is a stunning and sought-after freshwater invertebrate known for its brilliant red-and-white coloration and peaceful temperament. Originally bred from the wild Bee Shrimp, this selectively bred variety has become a favorite among aquascapers and shrimp enthusiasts alike.

Perfect for nano and planted aquariums, Crystal Reds help maintain a clean ecosystem by grazing on algae and biofilm. Their striking contrast against green plants and dark substrate makes them a true showpiece in any freshwater tank.

Care Sheet

Scientific Name: Caridina cantonensis var. “Crystal Red”
Common Name: Crystal Red Shrimp (CRS)
Origin: Taiwan (selectively bred from Bee Shrimp)
Difficulty: Moderate
Temperament: Peaceful
Lifespan: 1.5–2 years
Size: Up to 1.25 in (3 cm)

Water Parameters

• Temperature: 70–78°F (21–26°C)

• pH: 6.0–7.2 (slightly acidic preferred)

• GH: 4–6 dGH

• KH: 0–2 dKH

• TDS: 100–200 ppm

Tip: Stability is key! Avoid sudden changes in temperature, pH, or TDS — Crystal Reds are sensitive to fluctuations.

Tank Setup

• Minimum Tank Size: 5 gallons (larger recommended for colonies)

• Substrate: Active buffering substrate (helps maintain lower pH)

• Filtration: Gentle sponge or canister filter with shrimp-safe intake guards

• Lighting: Low to moderate

• Decor: Live plants, mosses (such as Java Moss), and hiding places like driftwood or shrimp tubes

Feeding

Crystal Red Shrimp are omnivores that graze on biofilm, algae, and detritus.
Supplement their diet with:

• High-quality shrimp pellets or granules

• Blanched vegetables (zucchini, spinach)

• Algae wafers and biofilm enhancers

Feed sparingly — remove uneaten food after a few hours to maintain water quality.

Behavior & Tank Mates

• Completely peaceful; best kept with other dwarf shrimp or small, non-aggressive fish (like rasboras or small tetras).

• Avoid large or predatory species.

• Excellent in species-only or planted shrimp tanks.

Breeding

• Breeding occurs readily in stable, clean, soft water.

• Females carry eggs for 3–4 weeks before releasing fully formed baby shrimp.

• Provide moss or fine plants for baby shrimp to hide and graze.

Key Benefits

• Beautiful red-and-white coloration for display tanks
• Peaceful and social — great for shrimp colonies
• Natural algae grazers and tank cleaners
• Pairs perfectly with planted aquariums
