What Type Of Fish Tanks Do Aquariums Use – Choosing The Perfect Tank

Starting an aquarium can feel a bit overwhelming, especially when you’re faced with a wall of different tanks at the local fish store. You might find yourself wondering, “Which one is right for me?” or “Do I need a specific type of tank for the fish I want?” It’s a common dilemma for new and experienced hobbyists alike.

Don’t worry, you’re in the right place! We’re here to demystify the world of fish tanks. Understanding what type of fish tanks do aquariums use is the crucial first step to creating a thriving aquatic environment.

This article will guide you through the various options available, from materials and shapes to specialized setups. By the end, you’ll have a clear understanding of which tank will best suit your aquatic ambitions and help your fish, shrimp, or plants flourish. Let’s dive in!

Understanding the Basics: Glass vs. Acrylic Aquariums

The very foundation of any aquarium is its material. The choice between glass and acrylic is one of the first decisions you’ll make, and each comes with its own set of advantages and considerations.

Glass Aquariums: The Traditional Choice

Glass tanks have been the standard in the hobby for decades, and for good reason. They are durable, scratch-resistant, and relatively inexpensive, especially for smaller sizes.

Glass maintains its clarity over time without yellowing, offering an unblemished view into your aquatic world.

They are also less prone to bowing or flexing under the pressure of water.

However, glass is heavy, especially for larger tanks, making them harder to move. They can also shatter if impacted severely, and they are not easily repaired if chipped or cracked.

Acrylic Aquariums: Modern and Lightweight

Acrylic tanks offer a contemporary alternative, known for their exceptional clarity and strength. They are significantly lighter than glass, often by as much as 50%, which can be a huge benefit for larger setups.

Acrylic is also much more impact-resistant than glass, making it less likely to shatter.

Scratches, while easier to incur, can often be buffed out with specialized kits, restoring the tank’s appearance.

On the flip side, acrylic is typically more expensive than glass, particularly for larger dimensions. It’s also more prone to scratching from abrasive cleaners or gravel, and can yellow slightly over many years if exposed to direct sunlight.

Standard Aquarium Shapes and Sizes for Every Space

Beyond the material, the shape and size of your aquarium play a significant role in its aesthetics, stability, and suitability for different inhabitants.

The Classic Rectangle: Versatility and Stability

The rectangular tank is by far the most common and versatile choice. Its straight lines and uniform dimensions make it easy to aquascape and provide ample swimming space for most fish.

Rectangular tanks are also highly stable, distributing the weight of the water evenly across the stand.

They are readily available in a vast range of sizes, from small desktop tanks to massive showpieces.

This shape is excellent for beginners, offering straightforward setup and maintenance.

Cube Aquariums: A Modern Aesthetic

Cube tanks are growing in popularity, offering a sleek, modern look. Their equal length, width, and height create a striking visual presence, often used for planted aquariums or for housing smaller, shoaling fish.

While aesthetically pleasing, cube tanks can sometimes limit horizontal swimming space for certain species.

Their depth can also make reaching the bottom for cleaning or aquascaping a bit more challenging.

Consider a cube if you have limited horizontal space but can accommodate height.

Bowfront and Corner Tanks: Adding Dimension

Bowfront tanks feature a curved front panel, adding a sense of depth and magnification to your aquatic display. They offer a unique viewing experience and can soften the lines of a room.

Corner tanks are specifically designed to fit into the corner of a room, maximizing space efficiency.

They often have a pentagonal or triangular footprint, offering a wide viewing angle from different parts of the room.

These specialized shapes can be a great way to integrate an aquarium seamlessly into your home decor.

Integrated Systems: All-in-One and Nano Tanks

For those seeking convenience or working with limited space, integrated systems and nano tanks offer fantastic solutions. These setups often come with filtration, lighting, and sometimes even heating built-in.

All-in-One (AIO) Aquariums: Convenience Redefined

AIO tanks are designed for simplicity. They typically feature a rear chamber that houses the filtration media, pump, and heater, keeping the main display area clutter-free.

This design is perfect for beginners, as it takes much of the guesswork out of equipment selection.

Maintenance is streamlined, and the overall footprint is often compact.

Just be sure to check the quality of the included equipment and ensure it’s suitable for your desired inhabitants.

Nano Tanks: Small Wonders

Nano tanks are typically defined as aquariums under 30 gallons, often much smaller (5-10 gallons are common). They are perfect for desktops, small apartments, or for keeping very specific, tiny inhabitants.

While their small size is a major advantage for space-saving, it also means that water parameters can fluctuate rapidly.

This requires more diligent monitoring and maintenance to keep the environment stable for delicate species.

Nano tanks are ideal for small shrimp colonies, a single Betta fish, or a highly specialized planted setup.

Advanced Setups: Sumps, Refugiums, and Custom Builds

As you gain experience, you might find yourself exploring more advanced aquarium designs that offer enhanced filtration, stability, and customization.

Sumps: The Hidden Powerhouse

A sump is an external reservoir, typically placed below the main display tank, that serves multiple critical functions. It increases the overall water volume of your system, which helps stabilize water parameters.

More importantly, sumps provide ample space for various filtration methods, including mechanical filtration (filter socks), biological filtration (bio-balls, live rock), and chemical filtration (carbon, GFO).

They also hide unsightly equipment like heaters, protein skimmers (for saltwater), and return pumps.

Sumps are almost a necessity for larger saltwater aquariums and are increasingly popular in freshwater planted tanks.

Refugiums: Nature’s Little Sanctuary

Often integrated into a sump, a refugium is a dedicated chamber designed to cultivate beneficial macroalgae (like Chaetomorpha) or small invertebrates.

In saltwater systems, refugiums help export nitrates and phosphates, naturally improving water quality.

They also provide a safe breeding ground for copepods and amphipods, which can serve as a natural food source for your main display inhabitants.

For freshwater, a refugium could be used to grow specific plants or house micro-fauna away from predatory fish.

Custom Builds: Dream Aquariums

For the truly dedicated hobbyist, a custom-built aquarium offers endless possibilities. These tanks are designed to specific dimensions, shapes, and often integrate seamlessly into cabinetry or architectural features.

Custom builds allow for unique viewing angles, specialized equipment housing, and the creation of truly one-of-a-kind aquatic masterpieces.

However, they come with a higher price tag and require careful planning and professional installation.

This option is for those with a clear vision and the budget to match.

what type of fish tanks do aquariums use for different inhabitants?

The inhabitants you choose for your aquarium will heavily influence the best tank type for your setup. It’s not just about size, but also about the specific needs of fish, shrimp, and plants.

Freshwater Community Tanks: Versatility is Key

For a typical freshwater community tank with a mix of peaceful species, a standard rectangular glass or acrylic tank is usually ideal. The linear swimming space is appreciated by many fish like tetras, rasboras, and even some smaller cichlids.

The key here is to choose a tank size that allows for adequate space for all inhabitants to grow and thrive without overcrowding.

A longer tank is often preferred over a taller, narrower one for community fish.

Many beginner aquarists choose a 20-gallon long or a 29-gallon standard for their first community setup.

Saltwater Reef Tanks: Specialized Demands

Saltwater reef tanks, especially those housing corals, require very specific conditions. These setups often feature sumps for advanced filtration and equipment.

Many reefers prefer tanks with minimal bracing across the top (rimless or low-iron glass) for unobstructed viewing and better light penetration.

The choice of what type of fish tanks do aquariums use for a reef system often leans towards robust construction and excellent clarity.

Acrylic can be popular for very large reef tanks due to its strength and lighter weight.

Planted Aquariums: Depth and Light

Planted aquariums (aquascapes) benefit from tanks that offer good depth for substrate and ample vertical space for plant growth. Low-iron glass tanks are often favored for their superior clarity, which truly makes the colors of plants pop.

Lighting is paramount in planted tanks, so a tank design that allows for easy installation of high-quality lights is beneficial.

Cube tanks can be excellent for vertical aquascaping, creating a forest-like effect.

Consider the height of your chosen plants when selecting your tank.

Shrimp and Nano Fish Tanks: Small but Mighty

For delicate shrimp colonies (like Neocaridina or Caridina) or tiny nano fish (e.g., chili rasboras, pea puffers), smaller tanks are often preferred. Nano tanks or even small cubes are perfect.

The smaller water volume allows for easier monitoring of parameters, which is critical for sensitive invertebrates.

An AIO nano tank can be a fantastic choice, providing a stable environment with minimal effort.

Ensure the filtration intake is shrimp-safe to prevent tiny inhabitants from being sucked in.

Choosing the Right Tank for Your Lifestyle and Goals

Ultimately, the best aquarium for you depends on a combination of factors unique to your situation. Don’t rush this decision; a well-chosen tank sets the stage for years of enjoyment.

Consider Your Space

Before anything else, measure your available space. Not just the footprint, but also the height and clearance for lighting and maintenance. Do you have a sturdy stand capable of supporting the immense weight of a filled aquarium?

Remember that a gallon of water weighs approximately 8.34 pounds, plus the weight of the tank itself, substrate, rock, and equipment.

A 55-gallon tank, for instance, can weigh over 600 pounds when full!

Never place a large aquarium on furniture not specifically designed for it.

Factor in Your Budget

Aquarium keeping can be an investment. Beyond the tank itself, you’ll need a stand, filter, heater, lighting, substrate, decor, water testing kits, and of course, the fish.

While a smaller tank might seem cheaper upfront, remember that larger tanks often offer more stability and forgiveness for beginners.

Set a realistic budget for both initial setup and ongoing maintenance.

Look for package deals or starter kits if you’re on a tight budget, but always verify the quality of included components.

Assess Your Commitment Level

Are you looking for a low-maintenance display, or are you eager to dive into complex aquascaping or advanced reef keeping? Your commitment to maintenance and learning will guide your tank choice.

Beginners might prefer a smaller, simpler setup like an AIO or a standard rectangular tank.

Experienced hobbyists might gravitate towards sumped systems or custom builds for greater control and customization.

Be honest with yourself about the time and effort you’re willing to invest.

Frequently Asked Questions About Aquarium Tank Types

Is a bigger fish tank easier to maintain?

Generally, yes. Larger tanks (typically 20 gallons and up) have a greater volume of water, which dilutes waste products more effectively and makes water parameters more stable. This means less drastic fluctuations and more time to correct issues compared to smaller tanks, which can crash quickly.

What is the most durable type of fish tank?

Acrylic tanks are generally considered more durable in terms of impact resistance and less prone to shattering than glass. However, glass is more scratch-resistant. The “most durable” depends on whether you prioritize resistance to shattering or scratching.

Can I put any fish in any type of tank?

No, absolutely not. The type and size of the tank must be appropriate for the species of fish you intend to keep. Factors like adult size, swimming patterns, schooling behavior, and territorial needs all dictate the minimum tank dimensions required for a healthy and happy life. Always research your chosen fish species first!

What’s the best type of tank for a beginner?

A standard rectangular glass tank between 20 and 40 gallons is often recommended for beginners. It offers good stability, ample space for a variety of fish, and is relatively easy to set up and maintain. All-in-One (AIO) tanks are also excellent choices for their integrated convenience.

Are rimless tanks good for beginners?

Rimless tanks offer a sleek, modern aesthetic and are popular, especially for planted or reef tanks. While beautiful, they can be more fragile than rimmed tanks and often require more precise leveling. For a complete beginner, a standard rimmed tank might offer a bit more peace of mind and robustness.
