Different Types Of Guppies – A Complete Guide To Colors, Tails, And
Most aquarium hobbyists start their journey with a single, colorful fish that seems to have endless energy.
You likely agree that few things are as mesmerizing as a well-planted tank filled with active, shimmering guppies.
In this guide, I promise to walk you through the vast world of different types of guppies so you can identify exactly what you’re looking at in the local fish store.
We will preview the various tail shapes, color patterns, and specific strains that make these “million fish” a staple in the hobby.
Classifying the Different Types of Guppies by Tail Shape
When you first start looking at different types of guppies, the most striking feature is often the tail.
Breeders have spent decades refining these shapes, and each one brings a unique aesthetic to your aquarium.
The Delta Tail (or Triangle Tail) is perhaps the most common variety you will see in high-end show tanks.
These tails are characterized by a wide, triangular shape that should ideally reach a 70-degree angle from the body.
If you prefer something a bit more elegant and flowing, the Veiltail is a classic choice.
Its tail is long and rectangular, trailing behind the fish like a delicate piece of silk in the water.
For those who enjoy a more aggressive or sharp look, the Lyretail is a personal favorite of mine.
The tail has a central notch, with the top and bottom rays extending outward like the arms of a lyre.
Don’t overlook the Double Swordtail, where the upper and lower rays extend into long, pointed filaments.
This variety is incredibly striking when the fish is displaying for a female or defending its territory.
The Spear Tail and Pin Tail are less common but offer a very sleek, aerodynamic look to the fish.
Lastly, the Round Tail is a hardy, more “natural” looking shape that is often found in more vigorous, active strains.
Choosing a tail shape isn’t just about looks; remember that larger, heavier tails can make swimming more difficult for the fish.
I always recommend providing plenty of low-flow areas in the tank if you choose varieties with massive finnage.
The Impact of Tail Size on Swimming
While a massive Fantail looks incredible, it acts like a sail in a high-flow aquarium.
If your filter output is too strong, your guppy will spend all its energy just trying to stay in one place.
I’ve found that using a sponge filter or a baffle on your power filter helps these long-finned beauties thrive.
Understanding Color Patterns: From Snakeskins to Tuxedos
Beyond the shape, the skin pattern is where the different types of guppies truly show their diversity.
One of the most popular patterns is the Snakeskin, which features a fine, lace-like pattern across the body.
In some strains, this pattern is so dense it looks like real reptile scales shimmering under your LED lights.
Then we have the Tuxedo guppy, which is a personal recommendation for beginners who want a sophisticated look.
These fish have a dark-colored posterior (the back half of the body) that contrasts sharply with a lighter front half.
The Cobra pattern is similar to the snakeskin but usually features larger spots and vertical bars on the peduncle.
If you are looking for something truly vibrant, keep an eye out for Mosaic patterns on the tail.
These tails look like stained glass windows, with irregular spots and splotches that connect in beautiful, chaotic ways.
For a more delicate appearance, the Grass pattern features tiny, pinpoint dots that resemble fine seeds scattered on the finnage.
I often tell my fellow hobbyists that the Leopard pattern is the most “wild” looking, with large, distinct dark spots.
Color isn’t just about the pattern; the base color of the body plays a huge role in the final look.
Albino guppies lack black pigment, resulting in red eyes and soft, pastel body colors that glow in a planted tank.
Metallic guppies, on the other hand, have specialized cells called iridophores that reflect light like a polished chrome bumper.
Why “Solid” Colors Are Harder Than They Look
You might think a solid red or solid blue guppy is simple, but achieving a pure solid color is a breeder’s challenge.
A true Full Red guppy should have no black spots or silver patches anywhere on its body or fins.
When you find a high-quality solid strain, the saturation of color can be absolutely breathtaking against green plants.
The Distinction Between Fancy Guppies and Endler’s Livebearers
In your search for different types of guppies, you will undoubtedly run into the term “Endler.”
Technically, these are Poecilia wingei, whereas the common guppy is Poecilia reticulata.
Endlers are generally smaller, much faster, and possess colors that are almost neon or fluorescent in nature.
They are incredibly hardy and are often the better choice for smaller “nano” tanks of 5 to 10 gallons.
However, be warned: guppies and Endlers can and will crossbreed very easily in the same aquarium.
The resulting offspring are known as Endler Hybrids, and they often carry the best of both worlds.
You get the incredible tail shapes of the fancy guppy and the intense, metallic colors of the Endler.
If you are a purist, you’ll want to keep these species in separate tanks to maintain their genetic integrity.
But if you just want a “skittles” tank of colors, mixing them can lead to some very interesting surprises.
Identifying a Pure Endler
Pure Endlers usually have very distinct “pea-cock” spots and a metallic green or orange sheen.
Their tails are almost always short and transparent, with “side swords” of bright color along the edges.
If the fish has a massive, flowing delta tail, it is almost certainly a hybrid and not a wild-type Endler.
How to Choose the Best Guppy for Your Aquarium
Now that you know the different types of guppies, how do you decide which ones to bring home?
First, consider your tank’s water parameters, specifically the hardness (GH) and alkalinity (KH).
Guppies are famous for being “easy,” but they actually prefer hard water with plenty of minerals for their health.
If you have very soft water, you might find that the fancy, long-finned varieties struggle with fin rot or “shimmies.”
I always suggest starting with Tequila Sunrise or Tuxedo varieties as they tend to be very robust.
Avoid buying fish that are hovering at the surface or have clamped fins at the store.
Healthy guppies should be constantly “pecking” at surfaces and displaying active, curious behavior.
If you are a beginner, I recommend getting all males to avoid the “guppy explosion” of babies.
Male guppies are the ones with the long fins and bright colors; females are typically larger and more drab.
However, if you want the full experience of the hobby, keeping a ratio of one male to two females is best.
This ensures that the male doesn’t stress out a single female with constant mating attempts.
The Importance of Quarantine
No matter which type you choose, always quarantine your new arrivals for at least two weeks.
Even the most beautiful show guppy can carry parasites like Camallanus worms or external flukes.
Trust me, it is much easier to treat a small quarantine tank than a 55-gallon community aquarium!
Essential Care Tips for Vibrant and Healthy Guppies
To keep the colors of your different types of guppies popping, diet and water quality are paramount.
I have found that a varied diet including high-quality flakes, frozen brine shrimp, and spirulina is key.
The carotenoids in shrimp and algae help enhance the reds and yellows in their skin and fins.
Water temperature should stay between 74°F and 82°F, though they can handle slight fluctuations.
The most important factor is consistency; guppies hate sudden changes in pH or temperature.
Weekly water changes of 20-30% will keep nitrates low and prevent the dreaded fin nipping that occurs in dirty water.
Adding live plants like Guppy Grass (Najas guadalupensis) or Java Moss provides natural hiding spots.
These plants also harbor “micro-fauna” that guppies love to snack on throughout the day.
If you notice your guppies’ colors fading, it’s often the first sign of stress or poor water quality.
Check your ammonia and nitrite levels immediately if you see a sudden change in their vibrancy.
Dealing with Aggression
You might be surprised to learn that guppies can sometimes be “nippy,” especially toward each other.
This usually happens if the tank is too small or if there aren’t enough hiding places.
Adding more tall plants or driftwood breaks up the line of sight and allows bullied fish to find peace.
Frequently Asked Questions About Guppy Varieties
What are the easiest types of guppies for beginners to keep?
Generally, “mutts” or mixed-strain guppies are the hardiest because they have a more diverse genetic pool.
If you want a specific strain, Tuxedo and Cobra varieties are known for being quite resilient.
Can different types of guppies live together in the same tank?
Yes, all varieties of Poecilia reticulata can live together and will likely interbreed if both sexes are present.
Just ensure they have similar temperature and water hardness requirements.
How long do fancy guppies typically live?
On average, a well-cared-for guppy will live between 2 and 3 years in a home aquarium.
Highly bred “show” strains may have slightly shorter lifespans due to the energy required to maintain large fins.
Why are my guppies’ tails splitting or fraying?
This is often a sign of either fin rot (bacterial) or physical damage from sharp decor or aggressive tank mates.
Check your water parameters and ensure you don’t have any plastic plants with jagged edges.
Do guppies need a heater?
Unless your home stays consistently at 75°F or above, a heater is highly recommended for stability.
Cold water can suppress their immune system and lead to fungal infections like Ich.
Conclusion
Exploring the different types of guppies is one of the most rewarding aspects of the aquarium hobby.
From the majestic Delta Tail to the intricate patterns of the Snakeskin, there is a variety for every taste.
Remember that while these fish are beautiful, they rely on you to provide hard water and a clean environment.
Whether you choose a purebred show strain or a colorful mix of Endler hybrids, you’re in for a treat.
Keep your water clean, your diet varied, and your tank well-planted, and your guppies will reward you with years of activity.
Don’t be afraid to start small—once you see your first set of fry, you’ll be hooked on these “million fish” forever!
Happy fish keeping, and I hope your new guppy tank becomes the centerpiece of your home!
