About the Red Mosaic Guppy
The Red Mosaic Guppy is one of the most spectacular fancy guppy varieties, prized for its brilliant crimson body and intricately patterned mosaic tail. Its large fan-shaped caudal fin features a delicate lace-like network of red, black, and translucent markings, creating a breathtaking display that makes it a standout centrepiece in any freshwater aquarium.
Developed through selective breeding, Red Mosaic Guppies are known for their vibrant colours, elegant finnage, and peaceful temperament. Males display the most intense colouration and flowing tails, while females are larger with more subtle colouring. Their active and inquisitive nature makes them a joy to watch as they explore every level of the aquarium.
Red Mosaic Guppies thrive in planted aquariums with stable water conditions, gentle filtration, and plenty of open swimming space. They are highly social and do well with other Guppies, Endlers, Corydoras, Platies, Mollies, peaceful Tetras, Rasboras, and freshwater shrimp. As prolific livebearers, they breed readily in home aquariums and are popular among hobbyists interested in selective breeding.
A varied diet of premium tropical flakes, micro pellets, spirulina, baby brine shrimp, daphnia, bloodworms, and other quality live or frozen foods will maximise their vibrant colours, fin development, and overall health.
Beautiful, peaceful, and easy to care for, the Red Mosaic Guppy is an exceptional choice for both beginner and experienced aquarists.

Common Mistakes
Keeping too many males together
Male Guppies constantly display to one another and may compete for females. A ratio of one male to two or three females is ideal if breeding is intended.
Poor water quality
Stable water conditions, regular maintenance, and efficient filtration are essential for healthy fish and vibrant colours.
Feeding only one type of food
A varied diet promotes stronger colouration, healthier fins, and improved breeding condition.
Housing with fin-nipping fish
Avoid Tiger Barbs and other fin-nipping species that may damage their large flowing tails.
Underestimating breeding rates
Red Mosaic Guppies reproduce quickly, so have a plan for managing fry if males and females are housed together.
