Did you know that a centerpiece isn’t just for lavish dining tables or art installations? In the world of aquascaping, a centerpiece fish is the jewel that turns your tank from a collection of fins and scales into a mesmerizing aquatic opera. Having my hands wet in the aquarium hobby for almost two decades, I’ve found that the right centerpiece fish is like the conductor of an orchestra—commanding attention, setting the tone, and bringing a unique harmony to its watery world.

Today, we’re looking into several options for your centerpiece fish. I’ll guide you through the whole process to ensure you find that fish—a veritable Beyoncé—that makes your tank truly unforgettable.

What Is a Centerpiece Fish?

A centerpiece fish is, in essence, the star of your underwater stage. It’s the fish that draws eyes and starts conversations; the one that lends your aquarium its unique identity. But it’s not just about aesthetics or size; the best centerpiece fish harmonize with their tankmates and their environment, just like a lead singer who knows when to step back and let the band shine.

Over the years, I’ve seen many centerpiece fish that are memorable for all sorts of reasons—color, size, unique features, or even distinct personalities. But let me tell you, it’s not always the flashiest or the biggest that take the title. Sometimes it’s the understated yet dignified characters that win the day, those that bring a sense of balance and intrigue to your tank.

What Makes a Good Centerpiece Fish?

As much as we’d all love to plop any eye-catching fish into our aquariums and call it a day, choosing a centerpiece fish requires a more nuanced approach. It’s not just about which species has the flashiest scales or the most dramatic fins—although, let’s be honest, those aspects certainly don’t hurt. So, what sets a good centerpiece fish apart from the rest of the shoal?


When you first lay eyes on a centerpiece fish, it should capture your attention in a way that other fish don’t. This could be through striking colors, unusual shapes, or even specific behaviors. You want this fish to be the star, the one that has your guests asking, “What is that fish, and where can I get one?”


As scintillating as a fish might be, if it doesn’t play well with others, it can disrupt the peace of your aquatic Eden. A good centerpiece fish should not only coexist with its tank mates but also complement them. This harmony often extends beyond mere temperament to factors like water parameters and feeding habits.

Visual Allure

The overall aesthetics are a critical factor. Brilliant colors, elegant swimming patterns, and a unique silhouette can make your fish the focal point of the tank. And remember, beauty isn’t just skin (or scale) deep; it should be a species that adds to the tank’s visual complexity by utilizing the space in a compelling way.

Low Maintenance (Relatively Speaking)

While no fish is entirely “set-and-forget,” the ideal centerpiece fish should be low maintenance and not require overly specialized care. You’re looking for a species that fits well with your current care regimen and doesn’t necessitate a whole host of new equipment or a steep learning curve.

The Crucial Interplay of Aquarium Size

The size of your aquarium isn’t just a cubic measurement of water—it’s an entire universe governed by intricate biological and aesthetic rules. Too often, aquarists underestimate how much the size of their tank influences the kinds of fish that can thrive within it. And when it comes to centerpiece fish, size matters in more ways than one!

The Volume Conundrum

The first, and perhaps most obvious, consideration is volume. Certain fish species need ample room to roam, especially if they’re of a larger breed. No matter how enchanting that Oscar Fish looks, placing it in a 10-gallon tank is a one-way ticket to Stressville—for both you and the fish.

Behavioral Patterns and Preferences

Fish have personalities, quirks, and preferences, believe it or not. Some are shy fish and prefer hiding spots, others love to dart about, while a few might enjoy lazily floating near the surface. The size and layout of your aquarium should accommodate these behaviors. Otherwise, your centerpiece fish might become a reclusive, unhappy wallflower—defeating the entire purpose.

Compatibility and Territory

Different fish species have varying territorial instincts. In a smaller tank, the likelihood of aggressive encounters skyrockets if a dominant species feels its territory is threatened. Conversely, in a larger environment, the same species might coexist harmoniously, each staking out its own niche in the tank’s ecosystem.

Vertical vs. Horizontal Space

Not all tanks are created equal; some are taller, others wider. Certain fish species prefer swimming at different water levels, and that vertical-horizontal dynamic can impact your choice of a centerpiece fish. For instance, Angelfish tend to prefer taller tanks due to their natural inclination to swim vertically, while Rainbowfish might be more at home in a horizontally elongated environment.

So, as you can see, the size of your aquarium is not merely a filter to narrow down your fish options—it’s a multifaceted parameter that impacts the well-being of your future aquatic superstar and its backup dancers. Consider it not as a limitation, but as a creative challenge.

Small Aquariums (Up to 10 Gallons)

The world of small aquariums is a universe brimming with possibilities, yet bound by the limitations of space. It’s like designing a tiny home; every inch counts. You want to pack it with eye-popping beauty without compromising the well-being of your aquatic friends. And yes, even in this pint-sized paradise, you can have a showstopping centerpiece fish that turns heads and sparks conversations.

Betta Fish

You know I’m partial to Bettas and probably figured it’s my favorite centerpiece fish. The Betta Fish, a.k.a. Siamese Fighting Fish, is a real showstopper with its bright colors and flashy fins. Trust me, it’s hard to walk by a tank with a Betta and not take a second look. They’re not just eye-candy, though; these fish have a strong personality to match.

Bettas are known for being feisty, so you’ve got to be a bit picky when choosing their tank mates. They’re like the divas of the fish world—gorgeous to look at, but they like their personal space. If you’re a fan of solo acts, a Betta fish could be your ideal centerpiece. And the best part? Betta Fish are very easy to take care of.

Dwarf Gourami

Dwarf Gouramis bring a burst of color and an almost zen-like calmness to community tanks. With their vivid blue or orange stripes, they truly are centerpiece material. They’re peaceful and can cohabit well with equally gentle species. Bonus: they’re labyrinth fish, which means they gulp air from the surface—a unique behavior that’s sure to grab attention.

Endler’s Livebearer

If you want a fish that’s as active as it is gorgeous, look no further than the Endler’s Livebearer. With its kaleidoscopic coloration and incessant swimming, it’s a living firework display and an excellent centerpiece fish. They’re hardy and breed easily, adding a dynamic element to your small aquarium.

Celestial Pearl Danio

For those who fancy a touch of elegance in a small package, the Celestial Pearl Danio is nothing short of a gem. With tiny, pearl-like spots set against a dark blue body, it’s like having a slice of the night sky swimming in your aquarium. They’re schooling fish, so while each individual is stunning, together they create a mesmerizing display.

Medium-sized Aquariums (20 to 30 Gallons)

In my nearly two decades of fishkeeping, I’ve found that medium-sized aquariums are often the sweet spot. They offer just the right mix of space and manageability. Trust me, once you’ve had some experience with smaller tanks, stepping up to a 20-gallon tank is like unlocking a new level in an epic fishkeeping adventure.

Here, we have the room to explore various fish species without feeling overwhelmed by the tank’s upkeep. So, what superstar fish can we consider for these versatile aquatic environments?

Angelfish are undeniably captivating, a centerpiece that draws your eye the moment you approach the tank. With their expansive, fan-like fins and intriguing patterns, they’re like living art. Yet, they’re more than just a pretty face. Angelfish are semi-aggressive and can be territorial, so they benefit from well-planned tank environments with plenty of hideaways.

Compatibility with other fish species is also something you’ll need to consider, as they’re prone to stake out their domain. I’ve found that their dramatic visual impact pairs well with their relatively straightforward care requirements—just keep an eye on the water parameters and potential tank mates..

Boeseman’s Rainbowfish

Boesman’s Rainbowfish, for me, are like tiny, living prisms—every turn they take sends flashes of color shimmering through the water. They’re lively, sure, but they also have a knack for peacekeeping; they get along well with most other peaceful fish species in a community tank.

What’s particularly intriguing is their schooling behavior; it’s like watching a fluid dance that changes form and hue with every beat. And speaking of beats, these fish are as hardy as they come. You won’t find yourself endlessly fiddling with water conditions. Just a well-maintained, stable environment, and they’ll reward you with a show that’s constantly changing.

Molly Fish


Molly Fish are something of an unsung hero when it comes to centerpieces—truly, they’re like the versatile actors who can play any role but still manage to stand out. With a dazzling array of colors, including gold, black, and even Dalmatian patterns, they’re a splash of living pigment in your tank.

They’re also quite low-maintenance. No fussing over complex diets or finicky water conditions; these fish are as resilient as they come. I’ve always found that their lively demeanor adds a buoyant atmosphere to any fish tank setup.

Corydoras Catfish

Now, if you’re someone who loves to break the conventional mold, let me introduce you to Corydoras Catfish—a different kind of star, the one that shines from the bottom of the tank. These little scavengers add an extra layer of complexity to your aquatic world. They are busybodies, constantly foraging and sifting through the substrate.

But they’re surprisingly social, often seen swimming together in small groups. I’ve observed that they bring a quirky charm and also serve a functional role, keeping the bottom of your fish tank clean. What’s not to love?

Honey Gourami

The Honey Gourami is like the laid-back cousin in the gourami family. With its soft, golden-orange hues, it brings a soothing visual element to any tank. Now, don’t let its quiet demeanor fool you; this fish has plenty to offer as a centerpiece. Unlike some other gouramis that can get a little territorial, this species is a generally peaceful fish. It makes for a harmonious tankmate but still has enough personality to capture your attention.

In my years of fishkeeping, I’ve found that it’s not always the loudest or flashiest fish that make the best centerpieces. Sometimes, it’s the subtle stars like the Honey Gourami that really bring a sense of balance and serenity to your aquatic setup. Plus, they’re pretty easy to care for, which makes them a solid choice for both newcomers and veteran fishkeepers alike.

Large Aquariums (30 Gallons and Above)

Large aquariums are for those of you who’ve decided to go all-in on this aquatic journey, and I’ve seen some awe-inspiring setups over the years, and the fish species we’re about to delve into are the ones that can truly do justice to these grand canvases.

Oscar Fish

First up, we’ve got the Oscar Fish, a species that’s practically a household name among fishkeepers with large tanks. These are sizable, robust fish, often reaching up to 14 inches. They’ve got this magnetic personality that’ll draw you in—each one has its own character, almost like a pet dog. I mean, some Oscars even recognize their owners and can be hand-fed!

But don’t get too complacent; they have specific care needs and can be territorial. So, remember to provide ample space and sturdy tank decorations that can withstand their explorations.

Discus Fish

If Oscars are the charismatic actors of the fish world, Discus Fish are the ethereal artists, gracing your fish tank with unparalleled colors—fiery reds, soothing blues, mesmerizing yellows. But, make no mistake, these fish are not for the casual hobbyist, as they require stable water conditions, a specific diet, and they’re prone to stress. I’ve always said, if you’re up for the challenge, the Discus Fish is the pinnacle of aquarium beauty.

Frontosa Cichlid

Stepping into the waterways of Africa, the Frontosa—a Lake Tanganyika native—exudes majesty with its striking appearance. Defined by its captivating stripes and regal nuchal hump, Frontosas bring a sense of grandeur to your large tank.

They’re a lot less aggressive than other cichlids and could share their kingdom with other non-aggressive, similarly-sized fish. I’ve had Frontosas before, and let me tell you, their quiet majesty is something to behold.

Clown Loach

The Clown Loach is vivid and vivacious, an interactive choice for those who appreciate both color and movement in their aquatic ensemble. They’re social, they school, and their alternating orange and black stripes bring a splash of color. Plus, they have this adorable habit of lying on their side when resting, which is always a fun spectacle.

Best kept in groups, these guys add an element of liveliness that never gets old. I can’t help but feel cheered up whenever I see my Clown Loaches zooming around.

The Final Splash

If you’ve made it this far, you’re clearly not just dipping your toes into the aquarium hobby—you’re diving in headfirst! As someone who has been around aquariums for nearly two decades, I can assure you the journey is as fulfilling as it is multifaceted.

A community fish tank is more than simply a collection of fish; it’s a living environment that’s been meticulously constructed over time. As a fishkeeper, you are not just a pet parent, but also an artist, scientist, and observer. From choosing your attractive centerpiece fish to fine-tuning the minute aspects of their environment, you’re creating a dynamic undersea scene that’s entirely unique to you.
