About Galaxy Pinto Shrimp

Galaxy Pinto shrimp represent one of the most sought-after and expensive varieties in the Taiwan Bee world. Their name comes from the distinctive star-like white spots on their cheeks that resemble a starry galaxy. Combined with their pinto or fishbone body patterns, Galaxy Pintos create a truly celestial appearance that captivates serious collectors. The galaxy pattern - those characteristic white spots on the head and cheeks - is what distinguishes these shrimp from regular pintos. While standard pintos show spotted or blotchy patterns on their bodies, Galaxy Pintos add this unique head spotting that gives them their name. The best specimens show abundant, well-defined galaxy spots alongside attractive body patterns. Galaxy Pintos command some of the highest prices in the shrimp hobby, with exceptional specimens selling for $400 or more. This reflects their rarity, the complexity of breeding for the galaxy pattern, and their status as prestige shrimp among serious collectors. The genetics behind the galaxy pattern remain somewhat mysterious, making consistent reproduction challenging even for experienced breeders.

Water Parameters for Galaxy Pinto Shrimp

Maintaining stable water parameters is crucial for the health and coloration of Galaxy Pinto Shrimp. 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 Galaxy Pinto Shrimp

  • Active buffering substrate is mandatory
  • Heavy planting with mosses and Bucephalandra
  • Sponge filtration is essential for protecting shrimplets
  • Stable, established tanks only for these sensitive shrimp
  • Include botanicals for biofilm and water conditioning

Care Tips for Galaxy Pinto Shrimp

  • Pristine, stable water conditions are essential for these high-value shrimp
  • RO water remineralized with Caridina GH+ is mandatory
  • Active buffering substrate must be well-maintained
  • TDS should remain stable between 100-150 ppm
  • Temperature stability is crucial - avoid all fluctuations
  • Quarantine new additions thoroughly before introduction
  • Only add to mature, stable tanks - never new setups

Feeding Galaxy Pinto Shrimp

  • Premium Caridina-specific foods are essential for valuable specimens
  • Biofilm is the dietary foundation - mature tanks only
  • Quality nutrition supports pattern development
  • Feed sparingly - water quality is paramount
  • Mineral supplements support healthy molting

Breeding Galaxy Pinto Shrimp

Difficulty
difficult
Clutch Size
10-18 eggs
Gestation
28-35 days
Special Requirements
Galaxy pattern genetics are complex and not fully understood. Galaxy spots don't always breed true - offspring may show varying degrees of galaxy pattern. Select breeding pairs with the strongest galaxy expression. High-quality Galaxy Pintos are rare and valuable.
  • Galaxy pattern genetics are complex and not fully predictable
  • Not all offspring will express the galaxy pattern
  • Select pairs with strongest galaxy expression for breeding
  • Small clutch sizes (10-18) are typical
  • High-grade Galaxy Pintos are rare even from quality parents

Galaxy Pinto Shrimp Grading System

Galaxy Pinto Shrimp 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 3

Standard Galaxy Pinto

Visible galaxy spots on cheeks with pinto body pattern. Galaxy pattern may be subtle.

Characteristics

  • Galaxy spots present
  • Pinto body pattern
  • Good overall appearance
  • Pattern may be subtle
Typical Price $30-60 each
Grade 2 of 3

High Grade Galaxy Pinto

Well-defined galaxy spots with excellent body patterning. Strong contrast and pattern clarity.

Characteristics

  • Clear galaxy spots
  • Excellent body pattern
  • Strong contrast
  • Well-defined markings
Typical Price $60-150 each
Grade 3 of 3

Extreme Galaxy Pinto

Exceptional galaxy pattern with perfect spot distribution and premium body markings. Collector-grade.

Characteristics

  • Perfect galaxy pattern
  • Premium body markings
  • Collector quality
  • Maximum pattern expression
Typical Price $150-400+ each

Grades listed from lowest to highest quality

Common Problems with Galaxy Pinto Shrimp

  • Galaxy pattern doesn't always express in offspring
  • High prices mean losses are particularly costly
  • Sensitivity to parameter fluctuations can cause deaths
  • Quality specimens are rare and difficult to source
  • Breeding outcomes are unpredictable
