If there’s one fish that truly lives up to the phrase “small but mighty,” it’s the guppy. These little swimmers may only be a couple of inches long, but they pack more color and character than many fish twice their size. Whether you’re a first-time aquarist or someone who’s already knee-deep in planted tanks, guppies are the kind of fish that never get boring.
But here’s the catch: once you dive into the guppy world, it’s easy to get overwhelmed. There are so many types—each with its own tail shape, color combo, and quirky name—that choosing just a few for your tank can feel like scrolling through a sushi menu for the first time.
So let’s break it down! This guide will walk you through the most popular types of guppy fish—by color, pattern, and tail style—plus give you some fun facts, care tips, and answers to common questions to keep your guppies happy and glowing.
Why Are There So Many Guppy Types?
Guppies (Poecilia reticulata) are a breeder’s dream. They reproduce quickly, pass on traits reliably, and come in a massive variety of colors and forms. In the wild, guppies tend to be a bit duller (more camouflage, less fashion show), but in captivity, selective breeding has turned them into underwater jewels.
What does this mean for you? A tank full of guppies can look like a living rainbow—and you get to mix and match different “types” based on:
- Color and body pattern
- Tail shape and fin size
- Other unique traits like large ears or compact size
Guppies by Color and Pattern
Let’s start with color. Guppies come in pretty much every shade you can imagine—some shimmer like metallics, others glow like neon signs. Here are some of the fan favorites:
1. Moscow Guppies
Imagine a sleek sports car… but in fish form. Moscow guppies are known for their deep, solid colors, usually dark blue, black, green, or even purple. The color is often so rich it covers their entire body and tail.
- Why people love them: They look mysterious and elegant—like tuxedo-wearing fish.
- Tip: They pop best against a lighter background or under strong LED lighting.
2. Cobra Guppies
These are the wild children of the guppy world. Cobra guppies have a unique snake-like pattern across their bodies, with swirling stripes or maze-like markings. They’re vibrant, energetic, and a bit chaotic—in the best way.
- Common colors: Orange, red, green, or a mix of all three.
- Fun fact: Their “cobra” pattern isn’t just random—it’s carefully bred in over generations.
3. Leopard Guppies
Leopard guppies have spots on their fins and bodies, usually black on a lighter or colorful background. Think of them as the cheetahs of your tank—sleek, fast, and spotted.
- Looks amazing with: Yellow, blue, or red base colors.
- Bonus: Their patterns often extend across their tails like a flowing canvas.
4. Blue Neon Guppies
These guppies look like they belong in a nightclub. Their electric-blue shimmer catches the light and gives them a glowing appearance that’s impossible to ignore.
- Best in tanks with: Dark gravel or backgrounds—it really makes them shine.
- Pro tip: They pair well with more neutral-looking fish for contrast.
5. Albino Guppies
Albino guppies are the soft-spoken beauties of the bunch. They lack dark pigments, which gives them a creamy white or pinkish color, along with signature red eyes.
- Mood: Soft, serene, and calming.
- Keep in mind: They’re a bit more light-sensitive, so make sure your lighting isn’t too intense.
Guppies by Tail Shape
Guppy tails come in all shapes and sizes—some short and round, others large and flamboyant. Tail shape affects how they swim, how fragile they are, and how dramatic they look while gliding through the water.
1. Delta Tail Guppies
One of the most popular types around, delta tails are wide, triangle-shaped fins that fan out like a cape. These guppies often look like they’re floating on silk.
- Perfect for: Tanks where you want high visual impact.
- Caution: These large tails can be prone to nipping, so avoid aggressive tank mates.
2. Lyretail Guppies
With tails shaped like a lyre (a musical instrument), these guppies have long, wispy extensions on both ends of their tails. They look graceful—almost like they’re dancing underwater.
- Swimming style: Slow and flowy.
- Ideal for: Peaceful, well-decorated aquariums.
3. Roundtail Guppies
Simple, sturdy, and charming—roundtail guppies are easygoing and tend to be hardier. Their tails are compact and rounded, which makes them strong swimmers.
- Great for beginners or those with more active community tanks.
4. Swordtail Guppies
Swordtail guppies have a long, narrow “sword” extending from the lower or both edges of the tail. They’re dramatic and eye-catching, with a shape that really stands out.
- Double swordtails are even more unique—watch them glide with elegance!
Other Unique Guppy Varieties
Not all guppies fit neatly into just “tail” or “color” categories. Some have extra flair that makes them especially fun to watch and collect.
1. Dumbo Ear Guppies
Dumbo guppies get their name from their oversized pectoral fins (those little ones near their gills), which resemble elephant ears. These fins wave as they swim, creating a whimsical effect.
- Common colors: Soft blues, whites, and pastel hues.
- Fun to watch: Their fins flutter like little wings!
2. Endler Guppies
Endlers are like the guppy’s little cousin—smaller, slimmer, and closer to their wild relatives. But don’t let their size fool you—they’re bursting with neon colors and loads of personality.
- Perfect for: Nano tanks or planted aquascapes.
- Bonus: Endlers tend to be more active and fast swimmers.
3. Fancy Guppies
This is a broad term for guppies that are particularly ornate—whether that means extravagant tails, unusual color blends, or rare fin combinations. Fancy guppies are often bred for shows or competitions.
- Think of them as: The supermodels of the fish world.
How to Keep Guppies Happy (and Colorful)
Once you’ve picked out your guppies, your next job is keeping them healthy and vibrant. Good news: guppies are fairly low-maintenance—but a little effort goes a long way.
Water Quality
- Temperature: 72–82°F (22–28°C)
- pH: Around 6.8 to 7.8
- Water changes: 20–30% weekly
- Filtration: Use a sponge or gentle hang-on-back filter
Good water quality helps your guppies avoid disease and keeps their colors from fading.
What to Feed Guppies
A colorful guppy is a well-fed guppy! A balanced diet helps them maintain their color and energy.
- Staples: Flake or micro-pellet food
- Treats: Frozen or live foods (brine shrimp, bloodworms, daphnia)
- Vegetables: Blanched peas, spinach, or spirulina flakes
Feed them once or twice a day—but just enough that they can finish in 1–2 minutes.
What to Know About Breeding
If you have both male and female guppies, expect babies—lots of them. Guppies breed like it’s their full-time job.
- Gestation period: 21–30 days
- Fry count: 20–50 (sometimes more!)
- Tip: Use a breeder box or give fry hiding spots with plants like java moss.
If you’re not planning on raising fry, stick to an all-male tank—or be prepared to rehome some babies.
