Guppies are some of the most sought-after freshwater fish in the aquarium hobby. These fish are known for their propensity to breed, and as a result, have resulted in hundreds of different line-bred color strains.
For folks looking to get their hands on some gorgeous fish, read on to discover 10 rare guppies that will impress in your freshwater tank. For each one we've listed its colors, size and care, and below the list you'll find the rarest guppy colors, the most popular breeds for beginners, and how to keep a rare strain looking the way it should.
Quick answer: what are the rarest guppies?
There's no single rarest guppy in the world. A strain is rare when only a few breeders keep the line going. Some of the hardest to find in the US are the Japan Winter Sky, Peacock Moscow, Midnight Blue Galaxy, Purple Dragon Platinum and Blue Panda Mini guppies.
Rarest colors: solid purple, true green and near-black blue. They're the hardest to find and to keep breeding true.

Rare Guppy Colors
Most pet-store guppies are reds, oranges, yellows and mixed colors. The colors serious breeders chase are the ones that are hard to get solid across the whole fish and hard to keep from one generation to the next:
- Purple: solid purple Moscows and the Purple Dragon Platinum above. See our purple Moscow guppy care guide.
- True green: Green Moscows and green lace lines. Most "green" guppies are really blue-green.
- Near-black blue: Midnight Blue Moscows and other dark Moscow lines.
- Platinum and albino: metallic-white and red-eyed lines in strong colors are less common than the standard ones.
"Dragon" is a trade name breeders use for several metallic, heavily scaled-looking lines rather than one strain, which is why you'll see Purple Dragon, Blue Dragon and Fancy Dragon guppies from different breeders.
Best Guppy Breeds for Beginners
If you're new to guppies, start with a strain that's colorful but forgiving, then move on to the rarer lines once your tank is running well. Moscow, cobra and snakeskin, tuxedo and koi guppies are among the most popular strains with hobbyists, and they're easy to find from breeders. Mixed-strain guppies, often sold as mutts or "melting pot" guppies, are the hardiest of all and a good way to learn how guppies breed.
For a smaller, bright alternative, Endler's livebearers are close guppy relatives that stay around an inch long.
Keeping a Rare Strain Pure
Guppies of different strains cross freely, and the fry of mixed strains usually lose the look you paid for within a generation or two. If you buy a rare strain to breed, keep it in its own tank, start with a trio or more from the same line, and pick the best-colored fish to breed from. Separate young males from young females early, since guppies can breed within a few months of birth.
Where to Buy Rare Guppies

FAQ
What is the rarest guppy?
There is no single rarest guppy in the world. Rarity depends on how few breeders keep a line going, so it changes over time. Strains that are hard to find in the US include the Japan Winter Sky, Peacock Moscow, Midnight Blue Galaxy, Purple Dragon Platinum and Blue Panda Mini guppies.
What are the rarest guppy colors?
Solid purple, true green and solid near-black blue are among the hardest guppy colors to find and to keep breeding true. Full platinum and albino lines in strong colors are also less common than the everyday reds, yellows and mixed-color guppies sold in pet stores.
What is the most popular guppy strain?
Moscow, cobra and snakeskin, tuxedo and koi guppies are among the most popular strains with hobbyists. Mixed-strain guppies, often sold as mutts or melting pot guppies, are the most common and usually the hardiest.
Are rare guppies harder to keep?
Not much. They need the same care as any guppy: a heated, filtered tank at about 72 to 82°F, a group with more females than males, and regular water changes. Some heavily line-bred strains are a little more delicate than mixed guppies, so buy from a breeder who raises them in conditions like yours.
Will rare guppies breed true?
Only if you keep the strain on its own. Guppies of different strains cross freely, and the fry of mixed strains usually lose the look you paid for within a generation or two. Keep each strain in its own tank and pick the best fish to breed.
Are Endlers guppies?
Endler's livebearers (Poecilia wingei) are close relatives of the common guppy (Poecilia reticulata), not the same species. They are smaller and cross easily with guppies, so keep Endler lines apart from guppies if you want to keep them pure.
Conclusion
This concludes our list of 10 rare guppies. While this list covered some of our favorites, there are still hundreds more strains available. If you're considering guppies for your tank, always make sure you're purchasing from a reputable breeder to ensure your fish are set up for a healthy and happy life.
