About White Orchid Shrimp

White Orchid shrimp from Lake Poso offer an elegant alternative to the more famous Cardinal shrimp. Their delicate white to cream coloration, sometimes accented with red markings, creates a different aesthetic from the bold red-and-white Cardinals. The 'Starry Night' variant, with its white spots scattered across a darker body, adds another visually stunning option to the Sulawesi lineup. Originating from Lake Poso in Sulawesi, Indonesia, White Orchids share the general Sulawesi care requirements but are often considered slightly easier than Lake Matano species like Cardinals. They still need high pH, warm temperatures, and abundant biofilm, but some keepers find them more forgiving of minor parameter variations. This relative adaptability makes them a reasonable starting point for hobbyists new to Sulawesi shrimp. The variety of White Orchid types available adds to their appeal. Standard White Orchids display cream to white coloration, while Starry Night specimens show distinctive spotted patterns reminiscent of a night sky. Some individuals display red markings on their rostrum or legs, adding color accent to the white base. This diversity means keepers can find White Orchids that suit their aesthetic preferences.

Water Parameters for White Orchid Shrimp

Maintaining stable water parameters is crucial for the health and coloration of White Orchid Shrimp. Sulawesi shrimp have unique requirements with higher pH and temperature needs compared to other dwarf shrimp.

Parameter Range Optimal
TDS 80-180 ppm 100-150 ppm
GH 4-8 dGH 5-7 dGH
KH 3-7 dKH 4-6 dKH
pH 7.5-8.5 7.8-8.2
Temperature 79-86°F (26-30°C) 81-84°F

Tank Setup for White Orchid Shrimp

  • Use inert substrates - NO active buffering substrates
  • Include plenty of rock surfaces for biofilm development
  • Lava rock, limestone, and coral rubble provide grazing surfaces
  • Strong lighting encourages biofilm and aufwuchs growth
  • Moderate flow replicates lake conditions
  • Minimum 3-6 months tank maturation before adding shrimp

Care Tips for White Orchid Shrimp

  • Requires Sulawesi parameters: HIGH pH (7.8-8.2) and HIGH temperature (81-84F)
  • RO water remineralized with Sulawesi-specific minerals is required
  • DO NOT use active/buffering substrates - they lower pH
  • Inert substrates (lava rock, limestone, coral rubble) work best
  • Considered slightly easier than Cardinals but still advanced-level
  • Tank must be mature with abundant biofilm before adding shrimp
  • Slow acclimation is essential (minimum 4 hours drip)

Feeding White Orchid Shrimp

  • Biofilm is the primary food source
  • Graze constantly on aufwuchs covering rocks and surfaces
  • Supplement sparingly with quality shrimp foods
  • Strong lighting encourages biofilm growth for feeding
  • Avoid overfeeding - biofilm should be the dietary foundation

Breeding White Orchid Shrimp

Difficulty
difficult
Clutch Size
10-25 eggs
Gestation
25-35 days
Special Requirements
White Orchid shrimp breed more readily than some other Sulawesi species. They still require mature tanks with abundant biofilm but show better breeding success than Cardinals for some keepers. Clutch sizes are moderate for Sulawesi (10-25 eggs).
  • Breed more readily than some Sulawesi species
  • Moderate clutch sizes (10-25 eggs) for Sulawesi
  • Stable, mature tanks show best breeding success
  • Shrimplets are small and require abundant biofilm
  • Colony growth is slow but steady in optimal conditions

White Orchid Shrimp Grading System

White Orchid 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 White Orchid

Good white/cream coloration. May have some tan or translucent areas.

Characteristics

  • White to cream body
  • Visible coloration
  • May have color variation
  • Good health indicators
Typical Price $12-22 each
Grade 2 of 3

High Grade White Orchid

Clean white coloration with minimal translucency. Clear pattern if Starry Night variant.

Characteristics

  • Clean white color
  • Minimal translucency
  • Good pattern definition
  • Strong appearance
Typical Price $18-35 each
Grade 3 of 3

Premium White Orchid

Maximum white saturation or perfect Starry Night spotting. Show-quality specimens.

Characteristics

  • Pure white or perfect spots
  • Show quality
  • Maximum color expression
  • Exceptional specimens
Typical Price $30-60+ each

Grades listed from lowest to highest quality

Common Problems with White Orchid Shrimp

  • Deaths from incorrect parameters (pH too low, temperature too low)
  • Insufficient biofilm in immature tanks
  • Rushed acclimation causing shock
  • Parameter instability leading to stress
  • Confusion with other white shrimp species requiring different care
