ABOUT THIS GUPPY
About the Blue Japan Guppy Fish
The Blue Japan Guppy Fish is defined by rich ocean-blue coloration, shimmering highlights, and broad flowing finnage. Its body can transition from lighter silver-blue reflections toward deeper blue tones near the tail, creating a smooth color gradient that becomes especially noticeable as the fish moves under aquarium lighting.
This variety fits naturally within our Premium Blue Guppy Collection , where different Fancy Guppy strains explore blue coloration through metallic bodies, patterned tails, contrasting markings, and decorative finnage. The Blue Japan Guppy takes a cleaner approach, placing the visual emphasis on saturated blue color and a large flowing tail rather than a heavily patterned design.

BLUE JAPAN VARIETY
What Makes the Blue Japan Guppy Fish Unique?
The visual character of the Blue Japan Guppy Fish comes from the way its coloration develops across the body and finnage. Lighter shimmering tones can appear toward the front of the fish before transitioning into richer blue across the rear body and expansive tail. Unlike Grass, Dragon, or Mosaic varieties that depend heavily on distinct markings, the Blue Japan Guppy creates impact through color depth, reflection, and flowing fin shape.
To compare different expressions of blue within the Tropicflow Guppy collection, explore the Blue Grass Fancy Guppy Fish , which introduces fine patterned finnage, or the Blue Dragon Guppy Fish , where blue coloration is paired with a more pronounced patterned appearance. The Half Black Blue Guppy Fish provides another contrast by combining vivid blue with a darker half-black body.
✨
Every Blue Japan Guppy Fish Is Unique
This is a Grower Pick variety, so product photos represent the general characteristics of the strain rather than the exact individual fish you will receive. Natural variation can occur in blue intensity, shimmering highlights, the transition between lighter and darker body tones, tail shape, dorsal development, and overall finnage. Age, genetics, aquarium lighting, shipping stress, and tank conditions can also influence how strongly the blue coloration appears.

Stability matters most.
Avoid chasing exact numbers with sudden water chemistry changes. A mature, cycled aquarium with stable parameters is generally safer than frequent rapid adjustments.
DAILY CARE
Creating a Healthy Guppy Aquarium
Ideal Tank Setup
Provide a fully cycled, filtered aquarium with plenty of open swimming space. Live plants can provide cover, visual barriers, and a more natural environment.
- Fully cycled aquarium
- Reliable filtration
- Open swimming space
- Live plants recommended
Feeding & Diet
Guppies are omnivores. Offer a varied diet rather than relying on only one food source.
- Quality micro pellets
- High-quality flakes
- Brine shrimp
- Daphnia and other suitable foods
Social Behavior
Guppies are active social fish and generally do well with other peaceful community species when tank size and water requirements are compatible.
- Active swimmers
- Peaceful community fish
- Enjoy group environments
- Avoid aggressive tank mates
Water Quality
Clean, stable water is one of the most important parts of Guppy care. Test the aquarium regularly and perform appropriate routine maintenance.
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Monitor nitrate
- Perform regular water changes
BEFORE DELIVERY
Prepare Before Your Guppy Arrives
Preparing the aquarium before delivery helps reduce unnecessary stress when your new fish arrives.
1
Cycle the Aquarium
Make sure the aquarium is established and biologically cycled before adding new fish.
2
Test the Water
Check temperature, pH, ammonia, nitrite, and nitrate before delivery day.
3
Prepare the Tank
Confirm filtration is running properly and provide plants or other appropriate cover.
4
Plan for Acclimation
Be available around delivery whenever possible so the fish can be brought indoors and acclimated promptly.

Understanding Guppy Sex Differences

- Popular for colorful display aquariums
GREAT FOR: COLOR & DISPLAY
Female Guppy
- Usually larger and fuller-bodied
- Typically develops shorter fins
- Color may be more subtle than males
- Often selected for groups and breeding
GREAT FOR: GROUPS & BREEDING
Important: Male Guppies may frequently pursue females. If keeping males and females together, provide adequate space, plant cover, and an appropriate group structure. Guppies are livebearers and can reproduce readily in suitable conditions.
DETAILED GUIDE
More Guppy Care Information
Water Parameters & Aquarium Maintenance
Maintain a stable temperature around 72–82°F and a pH around 6.8–7.8.
Ammonia and nitrite should remain at 0 ppm. Monitor nitrate and perform routine water changes appropriate for your aquarium's stocking level and filtration.
Avoid making large, sudden adjustments to temperature or water chemistry. Stable conditions are especially important for newly introduced fish.
What & How Often Should I Feed My Guppies?
Feed small portions of high-quality foods that your Guppies can consume within a short period. Avoid allowing large amounts of uneaten food to accumulate in the aquarium.
A varied diet may include quality micro pellets, flakes, brine shrimp, daphnia, and other appropriately sized foods.
Guppy Tank Mates
Guppies generally work best with peaceful, appropriately sized community fish that have compatible water requirements.
Potential tank mates may include peaceful Corydoras catfish, compatible small community fish, and suitable aquarium snails such as Nerite snails. Compatibility can vary depending on aquarium size, stocking, individual behavior, and water conditions.
Adult Neocaridina shrimp may also be an option in a planted tank, but guppies can eat shrimplets. Dense plant cover provides hiding places without guaranteeing their survival.
Keeping Male & Female Guppies Together
Guppies are livebearers and can reproduce readily. Male Guppies may frequently pursue females, so mixed-sex groups require adequate space, cover, and thoughtful group management.
If you do not want fry, consider keeping a same-sex group instead of intentionally mixing males and females.
How to Acclimate a Newly Arrived Guppy
Bring the shipment indoors promptly after delivery. Keep aquarium lighting low and avoid unnecessary handling while the fish is adjusting.
Gradually acclimate the fish to the aquarium's temperature and water conditions. Avoid sudden changes in temperature or chemistry.
Once introduced, allow the fish time to settle before feeding heavily or disturbing the aquarium.
What Is Normal After Shipping?
Newly shipped Guppies can temporarily appear pale, less active, or stressed after transit. Color and activity may improve as the fish adjusts to stable aquarium conditions.
Observe new arrivals carefully. If you notice persistent abnormal behavior or other concerns, check water parameters and document the fish and aquarium conditions.
Every Aquarium & Every Fish Is Different
These care recommendations are general guidelines. Aquarium size, stocking level, filtration, genetics, age, individual behavior, and local water chemistry can affect the needs of your fish.

One guppy seemed weak at first, so I kept it in quarantine overnight. It recovered well and now the whole group is healthy.
I keep several guppy strains and these were a nice addition to my collection. Good color, healthy bodies, and no damaged fins.
Really nice quality guppies. The colors became much stronger after a few days in my planted tank.
Exactly as described. Packaging was superb! Fast delivery. He is a beautiful and healthy baby boy
Easy ordering process and good packaging. My guppies arrived safe and started eating within a few hours.
