The Blue Tanzanite Guppy Fish is especially distinctive for its concentrated sapphire-blue coloration around the crown of the head. This vivid blue focal point is paired with a subtler metallic body, creating an appearance that can look dramatically different depending on the viewing angle and aquarium lighting.
This variety is part of our Fancy Guppy Fish collection , where different strains showcase a wide range of colors, patterns, and fin traits. The Blue Tanzanite Guppy stands apart by placing much of its visual emphasis near the head rather than relying entirely on a highly patterned or brightly colored tail.
The defining character of the Blue Tanzanite Guppy Fish comes from the placement of its coloration. Instead of spreading intense blue evenly across the entire body, this variety can show a concentrated sapphire-blue area around the crown of the head, supported by more subtle metallic tones through the body. This creates a strong focal point from above and gives the fish a very different visual balance from Guppies whose brightest coloration is concentrated mainly in the tail.
To compare other expressions of blue coloration, explore the Blue Japan Guppy Fish , which places more emphasis on rich blue coloration across the body and flowing tail. You can also compare the Blue Topaz Fin C Guppy Fish , where brilliant blue coloration is paired with an elongated lower fin for a more flowing silhouette.
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 sapphire-blue intensity, the size and placement of the crown marking, metallic body sheen, body coloration, tail shape, dorsal development, and overall finnage. Age, genetics, aquarium lighting, shipping stress, and tank conditions can also influence how strongly these traits appear.
If you enjoy the concentrated sapphire-blue coloration and metallic appearance of the Blue Tanzanite Guppy Fish, explore our Fancy Guppy Fish collection to discover more Blue Guppies, metallic varieties, fancy-fin Guppies, and colorful patterned strains for your freshwater aquarium.
Everything you need to help your new Guppies settle in, stay healthy, and thrive in your aquarium.
Avoid chasing exact numbers with sudden water chemistry changes. A mature, cycled aquarium with stable parameters is generally safer than frequent rapid adjustments.
Provide a fully cycled, filtered aquarium with plenty of open swimming space. Live plants can provide cover, visual barriers, and a more natural environment.
Guppies are omnivores. Offer a varied diet rather than relying on only one food source.
Guppies are active social fish and generally do well with other peaceful community species when tank size and water requirements are compatible.
Clean, stable water is one of the most important parts of Guppy care. Test the aquarium regularly and perform appropriate routine maintenance.
Preparing the aquarium before delivery helps reduce unnecessary stress when your new fish arrives.
Make sure the aquarium is established and biologically cycled before adding new fish.
Check temperature, pH, ammonia, nitrite, and nitrate before delivery day.
Confirm filtration is running properly and provide plants or other appropriate cover.
Be available around delivery whenever possible so the fish can be brought indoors and acclimated promptly.
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.
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.
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.
Guppies generally work best with peaceful, appropriately sized community fish that have compatible water requirements.
Potential tank mates may include peaceful Corydoras, compatible small community fish, and suitable aquarium snails. Compatibility can vary depending on aquarium size, stocking, individual behavior, and water conditions.
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.
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.
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.
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.

Never a disappointment when ordering from here!
These blue guppies are spectacular and a colorful addition to my guppy aquarium! I will always order from TropicFlow for all my hobby needs!
All came alive but mostly all males ordered again July 3 still have heard nothing π all where healthy and look great home my new order has more female's π
Healthy, active, so colorful and very huge size. Tropicflow really packs them right.
Very happy with my order. Fish came healthy and started swimming right away. Highly recommend this store.
Tanzanite and metal lace are sooo gorgeous! I want a tank full of them!
The package π¦ arrived late, I was terrified that every fish and snail would be passed due to the Arizona heat when I open the package the cooling ice was completely melted, and the box was very warm. When I took them out, they were barely hanging on to life. And one of the guppies had babies.
They look really blue in the picture but mine are basically black.
Order 5 tanzanite blue guppies. One male arrived with a destroyed dorsal fin and the other male was not even the correct type, its a black/blue tuxedo. Disappointed for sure. Hoping the one, correct, male makes it and doesn't succumb to his injury.
