🐠 What is a White Mosaic Guppy?
The White Mosaic Guppy (Poecilia reticulata) is a selectively bred strain of guppy known for its pure white or platinum-like body color paired with a mosaic pattern on the tail and sometimes the dorsal fins. The mosaic effect typically includes a mix of light hues, with a net-like or patchy pattern that resembles stained glass.
Common Names:
- White Mosaic Guppy
- Platinum Mosaic Guppy
- Snow Mosaic Guppy
- Ice Mosaic Guppy
🌈 Appearance and Coloration
The standout feature of the White Mosaic Guppy is its unique contrast of clean white or metallic body tones with an artistically patterned tail. This makes them visually appealing in both planted and minimalist tanks.
Distinguishing Features:
| Feature | Description |
|---|---|
| Body Color | White, platinum, or pearlescent |
| Tail Pattern | Mosaic pattern (light blue, gray, or pale pink) |
| Fin Type | Long, flowing caudal and dorsal fins |
| Size | Male: 1.5 inches; Female: 2.5 inches |
| Eye Color | Black or silver-gray |
Tail Shape Variants:
- Fan Tail
- Delta Tail
- Ribbon Tail
- Lyretail (less common in mosaics)
The mosaic pattern refers to the irregular, reticulated design on the tail fin, resembling broken tiles or a stained-glass window. In White Mosaic Guppies, this pattern is typically subtle and blends beautifully with their pale coloration.
🧬 Genetics of White Mosaic Guppies
The White Mosaic Guppy is the result of selective breeding over many generations. Breeders focus on enhancing the intensity of the white body and the complexity of the mosaic tail pattern.
Genetic Traits:
- Leucism or light pigmentation governs the white body color.
- The Mosaic tail gene affects tail design and spotting.
- Mosaic pattern is often sex-linked and appears more prominently in males.
- The body color can also be influenced by platinum or albino genes depending on the strain.
Breeding these guppies requires careful selection to maintain purity of color and ensure consistent mosaic patterns in future generations.
🏠 Ideal Tank Setup for White Mosaic Guppies
White Mosaic Guppies are hardy and adaptable but show their best colors in a clean, well-lit aquarium.
Recommended Tank Conditions:

| Tank Size | Minimum 10 gallons (38 liters) |
| Temperature | 74°F – 82°F (23°C – 28°C) |
| pH Level | 6.8 – 7.8 |
| Water Hardness | 8 – 12 dGH |
| Filtration | Sponge filter or hang-on-back filter |
| Lighting | Moderate to high (for color enhancement) |
Setup Tips:

Ideal Food Types:
- Flake food: High-protein guppy-specific flakes
- Micro pellets: Small and easy to digest
- Live food: Baby brine shrimp, daphnia, mosquito larvae
- Frozen food: Bloodworms, tubifex worms, Mysis shrimp
- Veggie matter: Blanched peas, spinach, spirulina flakes
Feeding Schedule:
- Feed 2–3 times daily in small amounts.
- Avoid overfeeding to maintain water clarity and prevent bloating.
- Occasionally fast them for 1 day/week to aid digestion.
❤️ Behavior and Tank Mates
White Mosaic Guppies are peaceful, social, and active swimmers. Their calm nature makes them ideal for community aquariums.
Behavior Traits:
- Peaceful and non-aggressive
- Highly active and curious
- Males may show mild territorial behavior during breeding
Best Tank Mates:
- Other guppy varieties
- Tetras (Neon, Ember, Cardinal)
- Platies, Mollies, Swordtails
- Corydoras catfish
- Shrimp (Cherry, Amano) and snails (Nerite, Mystery)
Avoid:
- Aggressive fish like Cichlids or Betta
- Fin-nippers like Tiger Barbs
Ensure a male-to-female ratio of 1:2 or 1:3 to prevent female stress from excessive courting.
🐣 Breeding White Mosaic Guppies
Breeding White Mosaic Guppies is both fun and rewarding. They are livebearers, meaning they give birth to live, free-swimming fry.
Breeding Conditions:
- Breeding tank size: 10–15 gallons
- Ideal ratio: 1 male to 2–3 females
- Temperature: 78°F – 80°F (25–26°C) for optimal reproduction
- Plants: Java Moss and floating plants for fry cover
Reproductive Cycle:
- Gestation: 21–30 days
- Fry count: 20–50 per birth (sometimes more)
- Signs: Gravid spot near rear darkens; female’s abdomen swells
Fry Care:
- Separate fry using a breeding box or nursery tank
- Feed baby brine shrimp, microworms, or crushed flakes
- Keep lighting dim and avoid strong current
- Frequent water changes are essential for fry survival
Over several generations, selective breeding helps improve the intensity of the white body and the detail in the mosaic pattern.
💧 Health and Maintenance
Proper care and water hygiene are vital to keeping your White Mosaic Guppies vibrant and healthy.
Common Guppy Diseases:
| Disease | Symptoms | Treatment |
|---|---|---|
| Ich (White Spot) | White dots, scratching behavior | Raise temp + anti-parasitic treatment |
| Fin Rot | Ragged fins, black edges | Antibacterial meds + clean water |
| Dropsy | Bloated belly, pinecone scales | Isolate + antibiotic treatment |
| Velvet Disease | Golden dusting, lethargy | Copper-based medication |
Prevention Tips:
- Change 20–30% of the water weekly
- Test water regularly for ammonia, nitrites, nitrates, and pH
- Quarantine new fish for 10–14 days
- Avoid overcrowding and overfeeding
