About Blue Bolt Taiwan Bee

Blue Bolt Taiwan Bee shrimp are arguably the most popular variety of Taiwan Bee shrimp, prized for their stunning blue coloration that ranges from delicate powder blue to intense steel blue. They emerged from Taiwan Bee breeding programs in the late 2000s and quickly became favorites among shrimp enthusiasts worldwide. What makes Blue Bolts particularly appealing is their relative accessibility compared to other Taiwan Bee varieties. While they still require the soft, acidic water conditions mandatory for all Caridina cantonensis, Blue Bolts are generally considered more forgiving than varieties like Shadow Pandas or extreme-colored Taiwan Bees. This makes them an excellent gateway species for keepers looking to transition from Crystal shrimp to Taiwan Bee varieties. Blue Bolt coloration varies significantly, which has led to an informal grading system based on color intensity. Light Blue Bolts show a subtle powder blue, while Deep or Extreme Blue Bolts display intense steel blue coloring that appears almost metallic under proper lighting. The genetics behind blue coloration can be complex, with offspring showing varying degrees of intensity even from high-grade parents.

Water Parameters for Blue Bolt Taiwan Bee

Maintaining stable water parameters is crucial for the health and coloration of Blue Bolt Taiwan Bee. As a Caridina species, they require more specific water conditions and are less tolerant of parameter swings.

Parameter Range Optimal
TDS 100-150 ppm 120-150 ppm
GH 4-6 dGH 4-5 dGH
KH 0-2 dKH 0-1 dKH
pH 5.8-6.8 6-6.4
Temperature 68-75°F (20-24°C) 70-73°F

Tank Setup for Blue Bolt Taiwan Bee

  • Active buffering substrate is mandatory for pH stability
  • Plant heavily with mosses and Bucephalandra
  • Sponge or matten filters protect shrimplets
  • Blue Bolts show beautifully against dark substrates
  • Include botanicals like Indian Almond Leaves for biofilm and tannins

Care Tips for Blue Bolt Taiwan Bee

  • RO water remineralized with Caridina GH+ is required - the same as all Taiwan Bee varieties
  • Active buffering substrate maintains necessary acidic conditions
  • Keep TDS between 100-150 ppm with stable parameters
  • Blue Bolts are considered slightly hardier than some Taiwan Bee varieties
  • Small weekly water changes (10%) with properly matched water
  • Avoid copper and other contaminants - use only shrimp-safe products
  • A well-established tank with mature biofilm is important for success

Feeding Blue Bolt Taiwan Bee

  • Feed quality Caridina-specific foods for optimal color and health
  • Some keepers believe certain foods enhance blue coloration
  • Biofilm is essential - ensure tank is mature before adding shrimp
  • Feed sparingly to maintain water quality - 2-3 times weekly
  • Provide mineral supplements and calcium for healthy molting

Breeding Blue Bolt Taiwan Bee

Difficulty
moderate
Clutch Size
12-22 eggs
Gestation
28-35 days
Special Requirements
Blue Bolts are considered one of the easier Taiwan Bee varieties to breed. Color intensity in offspring varies - selecting the bluest parents improves results over generations. Can be crossed with other Taiwan Bees, producing various color outcomes.
  • Blue Bolts breed more readily than some other Taiwan Bee varieties
  • Select the deepest blue parents to improve offspring color intensity
  • Color intensity varies in offspring - culling maintains colony quality
  • Can cross with other Taiwan Bees; red crosses may produce various colors
  • Gestation is 28-35 days with clutches of 12-22 shrimplets

Blue Bolt Taiwan Bee Grading System

Blue Bolt Taiwan Bee are commonly graded based on color intensity, coverage, and pattern quality. Higher grades typically command higher prices and are the result of selective breeding.

Grade 1 of 4

Light Blue Bolt

Entry-level Blue Bolts with lighter powder blue coloration. Blue may be concentrated on the head with lighter body.

Characteristics

  • Powder blue coloring
  • Blue concentrated on head
  • Body may be lighter
  • White markings possible
Typical Price $10-20 each
Grade 2 of 4

Standard Blue Bolt

Good blue coloration throughout the body with consistent coverage. The most common grade available.

Characteristics

  • Consistent blue coverage
  • Good color saturation
  • Even coloring head to tail
  • Clean appearance
Typical Price $15-30 each
Grade 3 of 4

Deep Blue Bolt

Intense, saturated blue coloring throughout. Premium specimens with exceptional depth of color.

Characteristics

  • Deep blue saturation
  • Intense coloring throughout
  • Steel blue tones
  • Excellent opacity
Typical Price $25-50 each
Grade 4 of 4

Extreme Blue Bolt

The highest grade with extraordinary blue intensity. Collector-quality specimens.

Characteristics

  • Maximum blue intensity
  • Perfect color coverage
  • Show-quality appearance
  • Breeding potential premium
Typical Price $40-100+ each

Grades listed from lowest to highest quality

Common Problems with Blue Bolt Taiwan Bee

  • Color intensity varies between individuals even from the same parents
  • Offspring may be lighter than parents - selective breeding helps
  • Deaths often result from parameter swings or contamination
  • Failed molts indicate mineral imbalance
  • Some Blue Bolts fade after shipping - color usually returns with good care
