When deciding on a fish tank to buy you will likely consider the time it will take to care for it. There isn’t an exact science to answer the question Which Fish Tank is Easiest to Maintain but we will provide you with the guidance you need to maximize the enjoyment of owning a fish tank with the least amount of time required to maintain a beautiful and successful aquarium.
The ease of maintaining a fish tank largely depends on its size, the type of fish you plan to keep, the filtration system you use, plant life, and your experience level. Generally, larger tanks are easier to maintain than smaller ones because the accumulation of waste takes longer, larger tanks are more forgiving of mistakes, and it is easier to establish a larger and more diverse living ecosystem that is self-cleaning.
Follow these guidelines to have a low maintenance fish tank:
- Keep your tank setup simple. The smaller the tank, the simpler the setup should be.
- Do not overpopulate your tank. The more fish you have, the more maintenance there is.
- Follow the one inch per gallon rule. The one inch per gallon rule has been around for decades, is the most popular approach to stocking aquariums with fish. At face value, it means that a five-gallon tank can hold five inches of fish. A ten-gallon tank, 10 inches, etc.
- This approach works as a guide but does not consider the unique needs of different fish species, the quality of water filtration, live plants, lighting, fish behavior like dominant expression or territorialism or even the shape of your tank.
- Many new aquarium owners mistakenly apply this rule to the size of the fish when purchased rather than the maximum size of the fish when they are mature. As the fish mature, they may become taller and wider which challenges the one inch per gallon rule.
- Choose fish that produce less waste. For example, neon tetra’s produce very little waste and don’t grow to a large size but goldfish produce a lot of waste, can become quite large, requiring more frequent water changes, water testing and filter changes.
- Add air bubbles to your tank. Fish thrive in oxygen rich water. More dissolved oxygen in the water means more surface area available to your fish. The natural lifecycle of your aquarium creates carbon dioxide which escapes your tank through gas exchange occurring at the surface of your tank.
- You can maximize the gas exchange by adding an air bubbler in the bottom of your tank.
- When the air pump creates bubbles, it increases the surface area of the water, enabling your tank to release more carbon dioxide and take in more oxygen.
- Improve your water quality. Consider adding live plants rather than decorative artificial ones. Live plants use waste as fertilizer and contribute to your biological filtration, further improving the capability of your aquarium to handle more fish.
- Biological filtration alone is not enough to keep your tank population in clear water, for that you need mechanical filtration also known as particulate filtration.
In general, your mechanical filter should run four times the total volume of water in the tank through the filter each hour. That means a 10-gallon tank requires at a minimum a filter rated at 40 gallons per hour. There is no danger of over-filtering your water so a larger or higher flow rate is fine if the fish can accommodate the added water movement.

Low maintenance small fish tank options:
- Betta Fish Tank (2.5 to 5 gallons): Betta fish are hardy and don’t require a large tank. They can thrive in a smaller, filtered tank with a heater. Regular water changes and monitoring water parameters are still important.
- Nano Reef Tank (10 to 20 gallons): If you’re interested in saltwater fish, a small nano reef tank with live rock and corals can be relatively easy to maintain. These tanks often have simple filtration systems and require regular testing of water parameters.
- Coldwater Tank (20 gallons or more): You can keep more small schooling fish like tetras, zebra danios and platies than the one inch of fish per gallon rule dictates if your filtration is good, you aren’t overfeeding, and you are consistent with your water changes.
- As you calculate the number of fish you can add to your tank consider that as fish length increases, body volume and waste production increase exponentially. For example, a 2-inch fish may have three or four times the mass and waste production of a 1-inch fish.
- Tropical Community Tank (20 gallons or more): A well-planned community tank with a variety of compatible tropical fish can be relatively easy to maintain. Adequate filtration, a heater, and regular water changes are necessary.
- Low-Tech Planted Tank (10 gallons or more): A planted tank with low-light, low-tech plants can be easy to maintain compared to high-tech setups. Live plants can help stabilize water parameters and reduce the need for frequent water changes.
Low maintenance large fish tank options:
- Paludariums: These tanks combine an underwater aquatic environment with a terrestrial environment above the waterline. They are ideal for keeping aquatic and semi-aquatic plants, as well as larger fish, amphibians and reptiles.
- Saltwater Reef Tanks: Reef aquariums are designed specifically for keeping coral reefs and marine fish. They require specialized equipment to maintain the water conditions necessary for coral growth and are typically larger to accommodate the diverse marine life and self-sufficient marine ecology.
- Freshwater Planted Tanks: These tanks are designed for growing aquatic plants along with fish. They require special lighting and substrate for plant growth and can be quite large to create lush underwater landscapes.
- Predator Tanks: For enthusiasts who want to keep predatory fish like large cichlids or predatory catfish, specialized tanks with thick glass or acrylic and strong filtration are necessary.
What Is the Easiest Fish Tank to Take Care Of?
The easiest fish tank to take care of is typically the smallest and simplest setup with proper filtration, air supply and adequate healthy bacteria.
The fish tank would look like this:
- It would be 10 gallons or smaller.
- Filtration: Invest in a simple, reliable aquarium filter to help keep the water clean and clear. Make sure to follow the manufacturer’s instructions for maintenance.
- Substrate: Choose an easy-to-clean substrate like aquarium gravel or sand. Avoid complex substrates that require frequent cleaning.
- Lighting: Use basic aquarium lighting that provides enough illumination for your fish and live plants, if you decide to include them. Timer-controlled lighting can help maintain a consistent day-night cycle for your fish.
- Water Parameters: Select fish species that are tolerant of a wide range of water conditions. Most beginner-friendly fish thrive in a temperature range of 72-78°F (22-26°C) and a pH level close to neutral (around 7.0).
- Fish Selection: Opt for hardy and beginner-friendly fish species like:
- Guppies
- Platies
- Mollies
- Swordtails
- Betta fish
- Zebra Danios
- Tetras (e.g., Neon Tetras or Cardinal Tetras)
- Corydoras Catfish
- Feeding: Feed your fish a high-quality, balanced diet and avoid overfeeding, which can lead to water quality problems.
- Regular Maintenance: Perform regular water changes (about 10-20% of the water volume every 1-2 weeks), clean the filter as needed, and monitor water parameters using a test kit.
- Avoid Overcrowding: As mentioned above, don’t overcrowd your tank with too many fish. Follow the 1 gallon of water for every 1 inch of fish rule (measured at adult size).
- Decorations and Plants: Keep decorations and live plants simple, as they can add to the maintenance workload. Artificial plants or easy-to-care-for live plants like Anubias or Java Ferns are good choices.
By following these guidelines and selecting low-maintenance fish and equipment, you can create an easy-to-care-for fish tank that provides enjoyment without requiring too much time and effort to maintain. Remember that even the simplest aquariums still require regular care and attention to ensure the health and well-being of your fish.
Is a Freshwater or Saltwater Tank Easier to Maintain?
Freshwater fish tanks are generally less complex than saltwater fish tanks requiring less time, less expertise and less expensive to maintain.
Here are some considerations for both types of aquariums:
Freshwater Tank:
Ease of Setup: Freshwater tanks are generally considered easier for beginners. They require less specialized equipment and are less complex to set up.
Cost: Freshwater fish and plants are often less expensive than their saltwater counterparts. This can make a freshwater tank more affordable.
Water Changes: Freshwater tanks typically require fewer water changes than saltwater tanks. This can make maintenance less time-consuming.
Fish Selection: Freshwater fish come in a wide range of species, including many hardy and beginner-friendly options. This can make it easier to find fish that are well-suited to your tank.
Water Chemistry: Freshwater tanks tend to have more stable water chemistry, making it easier to maintain proper conditions for fish and plants.
Saltwater Tank:
Complexity: Saltwater tanks can be more complex to set up and maintain, especially if you’re new to aquarium keeping. They require specific equipment, including protein skimmers and sumps, and may involve more intricate maintenance routines.
Cost: Saltwater aquariums can be more expensive to set up and maintain due to the cost of equipment, marine fish, and live corals. The initial investment can be substantial.
Water Quality: Maintaining stable water parameters, including salinity and pH, is crucial in saltwater tanks. This may require more precise monitoring and adjustments.
Livestock Selection: Saltwater tanks offer a wide variety of colorful fish and corals, but many of them are sensitive to water conditions and may require more attention and care.
Maintenance: Saltwater tanks often require more frequent water changes and more involved maintenance routines, such as regular testing and adjusting of water parameters.
How Do You Set Up a No Maintenance Fish Tank?
There is no such thing as a “No Maintenance Fish Tank”. All fish tanks with living animals, plants, bacteria and microbes require some maintenance. Establishing a low-maintenance fish tank is an attainable goal.
Expert Tips:
- Invest in a good-quality filter and follow the manufacturer’s recommendations for maintenance.
- Use a gravel vacuum to clean the substrate during water changes.
- Monitor water parameters (pH, ammonia, nitrite, nitrate) regularly and take appropriate action if they become imbalanced.
- Perform routine water changes to remove waste and maintain water quality.
- Avoid overstocking your tank, as overcrowding can lead to more maintenance issues.
- Quarantine new fish to prevent the introduction of diseases to your main tank.
- Research the specific needs of the fish and plants you want to keep ensuring they are compatible with your tank setup and maintenance routine.
- Ultimately, the ease of maintaining a fish tank is determined by your commitment to regular maintenance tasks and your willingness to learn about the specific requirements of the fish and plants in your aquarium.
In summary:
{f you’re a beginner or looking for a low-maintenance option, a freshwater tank is generally easier to manage. However, if you’re experienced, passionate about marine life, and willing to invest the time and resources required, a saltwater tank can be a rewarding and beautiful addition to your home.
Ultimately, the choice between freshwater and saltwater fish tanks should align with your interests, commitment level, and willingness to invest in both time and money for maintenance. The saltwater fish tank on our main page is one of my favorite aquariums and it is large enough to create a balanced ecosystem and lower maintenance cycles. My children prefer the simplicity, ease of maintenance and beauty of their smaller freshwater fish tanks.
