What Fish Tank Should I Get – ? The Expert’S Guide To Choosing Your Pe
Walking into a local fish store can be overwhelming. With rows of glass boxes ranging from tiny desktop bowls to massive, wall-sized displays, asking yourself what fish tank should I get is the most important first step you can take.
Choosing the right aquarium isn’t just about picking the one that looks coolest. It’s about matching a habitat to the specific needs of the livestock you intend to keep. A mistake here can lead to unstable water chemistry, stressed fish, and an uphill battle for you as a hobbyist.
Don’t worry—getting it right the first time is easier than you think. In this guide, we’ll break down exactly how to evaluate your space, your budget, and your goals to find the tank that will help your aquatic ecosystem thrive for years to come.
Understanding Your Goals: What Fish Tank Should I Get?
Before you worry about the brand or the glass type, you must define your “why.” Are you looking for a relaxing centerpiece for your living room, or are you hoping to breed rare shrimp species?
If you are a beginner, the biggest myth in the hobby is that smaller tanks are easier to maintain. In reality, the opposite is true.
Larger volumes of water are far more forgiving. If you accidentally overfeed or a filter stops working, a 50-gallon tank will stay stable much longer than a 5-gallon nano cube.
Matching the Tank to the Livestock
Think about the fish you love. Do they need long stretches of horizontal space to swim? Are they jumpers? Do they require specific water parameters like high flow or soft, acidic conditions?
For example, a school of active Tetras needs a longer tank (like a 20-gallon long) to dart back and forth. Conversely, a single Betta might prefer a smaller, heavily planted 5-10 gallon environment where they can build bubble nests in peace.
Glass vs. Acrylic: Weighing the Materials
When deciding what fish tank should I get, you will inevitably face the choice between glass and acrylic. Both have pros and cons that directly impact your daily maintenance routine.
The Case for Glass
Glass is the industry standard for a reason. It is scratch-resistant, meaning you can use magnetic algae scrapers or razor blades to clean the panes without fear of ruining the clarity.
It is also generally more affordable and holds its shape perfectly over time. However, it is heavy and can be prone to chipping or cracking if bumped by a heavy piece of hardscape like rock or driftwood.
The Benefits of Acrylic
Acrylic is much lighter and stronger than glass. It is often used for custom shapes or very large tanks because it can be molded and bonded seamlessly.
The major downside? Acrylic is a magnet for scratches. Even a tiny piece of sand caught in your cleaning pad can leave a permanent mark. If you are a perfectionist who can’t stand a scratched view, stick with glass.
The “Everything Included” Kit vs. Building Your Own
New hobbyists often gravitate toward “all-in-one” (AIO) kits. These come with a tank, light, filter, and sometimes even a heater.
These kits are fantastic for those who want a “plug-and-play” experience. However, be cautious: the internal filters and lights in cheap kits are often underpowered for anything beyond basic plants or low-bioload fish.
The Custom Approach
Building your own setup allows you to select high-quality components. You can choose a canister filter that provides superior biological filtration or an LED light fixture capable of growing lush, demanding carpeting plants.
While this route requires more research, it prevents the “double-buy” trap—where you buy a kit, realize it isn’t sufficient, and end up spending more money to replace the equipment anyway.
Considering the Footprint and Weight
Many people forget to factor in the physical weight of a full aquarium. Water weighs roughly 8.3 pounds per gallon. Once you add sand, rocks, and equipment, a 50-gallon tank can easily weigh over 500 pounds.
Structural Integrity
Always ensure your stand is rated for the weight of a full tank. Never place a large aquarium on a standard piece of furniture like a bookshelf or a dresser unless you are certain it can handle the load.
Also, consider your floor. If you live in an apartment on an upper floor, stick to tanks under 30 gallons unless you’ve verified your floor’s weight-bearing capacity.
The Importance of Maintenance and Access
When you ask yourself what fish tank should I get, consider how you will actually clean it. A tank that is 24 inches deep is beautiful, but if you have short arms, you will struggle to reach the bottom to trim your plants or catch a fish.
Rimless vs. Rimmed Tanks
Rimless tanks offer a sleek, modern, “floating” look that is incredibly popular in aquascaping. However, they usually require thinner glass or specific structural reinforcement.
Rimmed tanks are traditional, durable, and often cheaper. They hide the water line and the top edge of the substrate, which can make maintenance feel a little less “high stakes.”
Common Mistakes to Avoid
- Ignoring the Cycle: No matter what tank you get, you must perform a nitrogen cycle before adding fish.
- Overstocking: Just because a tank can hold 10 fish doesn’t mean it should. Always calculate your bioload.
- Skimping on Filtration: Always buy a filter rated for a higher volume than your tank size. It’s better to have too much filtration than not enough.
Frequently Asked Questions
Is a 10-gallon tank a good starter size?
A 10-gallon tank is excellent for a single Betta or a small colony of shrimp. However, it requires weekly water changes to keep the chemistry stable.
How do I know if my stand is strong enough?
If the stand isn’t specifically designed for an aquarium, it is a risk. Particle board often warps when it gets wet, which can lead to catastrophic tank failure. Always use a dedicated aquarium stand.
What fish tank should I get for a beginner who wants a community tank?
A 20-gallon long tank is widely considered the “gold standard” for beginners. It provides enough volume to be stable and enough horizontal space for a variety of small, peaceful schooling fish.
Do I need a lid for my aquarium?
Yes, especially if you keep active species. Many fish are natural jumpers and will jump out if startled. A lid also reduces evaporation and keeps dust or household chemicals out of your water.
Final Thoughts: Your Journey Begins Here
Choosing the right aquarium is the foundation of your success. Whether you settle on a rimless nano tank for your desk or a large, planted community setup, the key is to prioritize the health of your future inhabitants over aesthetic trends.
Remember, the best tank is one that you can maintain consistently. If you keep the water clean and the equipment running well, your aquarium will become a thriving piece of nature that brings you peace and joy for years to come.
Now that you know what to look for, take your time, measure your space, and enjoy the process of setting up your new underwater world!
