ABOUT THIS GUPPY
About the Half Black Blue Guppy Fish
The Half Black Blue Guppy Fish combines deep Half Black body coloration with vivid blue finnage for a clean, high-contrast appearance. The darker rear body creates a strong visual base, while cool blue tones extend into the tail and fins, becoming especially noticeable as the fish moves beneath aquarium lighting.
This variety belongs naturally within our Half Black Guppy Collection , where the signature dark body pattern is paired with several different color expressions. Among these varieties, the Half Black Blue Guppy creates a cooler-toned display by combining the dark Half Black section with bright blue finnage.

HALF BLACK BLUE VARIETY
What Makes the Half Black Blue Guppy Fish Unique?
The defining character of the Half Black Blue Guppy Fish comes from the transition between its darker body section and vivid blue finnage. Instead of spreading one uniform color from head to tail, this variety uses a strong division of color to create visual depth. The Half Black area gives the fish a darker foundation, while the blue tail and fins become the focal point, producing a balanced two-tone appearance as the fish swims.
For the closest variation, explore the Half Black Blue Ribbon Fin Guppy Fish , which keeps the same Half Black and blue color relationship while adding elongated Ribbon-style finnage. You can also compare the Half Black Yellow Guppy Fish for a warmer color expression, or the Half Black White Guppy Fish for a crisp black-and-white interpretation of the same Half Black family.
β¨
Every Half Black Blue 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 differences can occur in blue intensity, depth and coverage of the Half Black area, the transition between body colors, tail shape, dorsal development, and overall finnage. Age, genetics, aquarium lighting, shipping stress, and tank conditions can also influence how strongly the dark and 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.
MALE OR FEMALE?
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 72β82Β°F and a pH around 6.8β7.8.
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.

Love my fish
These guppies are beautiful and healthy!
These guppies are beautiful and arrived healthy. They're wonderful addition to my aquarium!
For close to two decades I've been getting "show quality Guppies" from three different IFGA breeders; truly the best of the best in the country. SO, what I'm about to say feels like blasphemy; but the Half Black Blue Delta Tail Guppies I just purchased are really nice. I'm curious to see what size they grow to, but otherwise I give these Guppies a 9 on a 10 scale.
All the fish arrived alive and are thriving!
These fish arrived healthy and vibrant! The pictures didnβt do them justice.
I received 5 guppy fish in great conditions. All looks wealth.
This is the most beautiful guppy. Graceful and happy.
Insulated, heat pack still warm, bags clean, and the guppies absolute fire.
Order Pack of 10 and they are happy and healthy
