Best Fish Tanks Buying Guide
Tank Size and Capacity
The size of your best fish tanks directly affects the types and number of fish you can keep. Smaller tanks, like 1- to 5-gallon setups, are ideal for a single betta or shrimp, while 10- to 20-gallon tanks offer more stability and room for community fish. Consider the available floor space and the adult size of your fish. A larger tank also dilutes waste more effectively, making water quality easier to maintain. For a deeper look at tank sizes, see our Fish & Aquariums section.
Filtration System
A reliable filter keeps the water clean and safe for your fish. Most starter kits include a power filter or cartridge system, but some models offer hidden or smart filtration. Look for tanks that provide mechanical, biological, and chemical filtration. For bettas and other low-flow fish, gentle filtration is important to avoid stressing them. The Marineland Portrait and Tetra ColorFusion kits are examples of tanks with well-designed filtration.
Lighting and Plant Growth
Proper lighting supports plant growth, enhances fish colors, and creates a natural day-night cycle. Many modern best fish tanks include LED lights with adjustable brightness or color-changing modes. If you plan to keep live plants, choose a tank with full-spectrum LEDs. The Aqueon starter kits and the smart M1 tank offer excellent lighting options. Avoid tanks with weak or non-submersible lights if you want a planted aquarium.
Ease of Maintenance
Regular water changes and filter cleaning are part of owning a fish tank. Look for features like easy-access lids, removable filter cartridges, and smooth surfaces that resist algae. Self-cleaning systems, like those in some 10-gallon kits, can reduce maintenance time. The Aqueon Smart Clean system and the 10-gallon set with self-cleaning filter are great choices for busy owners.
Material and Build Quality
Fish tanks are typically made of glass or acrylic. Glass tanks are scratch-resistant and offer clear viewing, while acrylic tanks are lighter and less prone to breakage. Rimless designs, like the NICREW nano tank, give a modern look but may require more careful handling. Consider the warranty and thickness of the glass or acrylic when making your decision.
Included Accessories
Many best fish tanks come as complete kits with filter, heater, lid, and sometimes even plants or decorations. A full kit can save you time and money, especially for beginners. Check what is included: some kits lack a heater, which is essential for tropical fish. The Tetra ColorFusion kit includes a heater, while the Aqueon starter kit does not. Always verify the accessories list before purchasing.

Frequently Asked Questions
What is the best fish tanks for beginners?
For beginners, we recommend a 10-gallon starter kit like the Aqueon or Tetra models. They include essential equipment and are large enough to maintain stable water parameters. Smaller tanks can be harder to keep stable, so a 10-gallon is a sweet spot for learning.
How often should I clean my best fish tanks?
Most tanks require a partial water change of 25-30% every one to two weeks, along with filter cartridge replacement every month. The exact schedule depends on the number of fish and the efficiency of your filtration. Self-cleaning systems can reduce the frequency.
Can I keep live plants in a starter kit?
Yes, many starter kits have LED lights that support low-light plants like Java fern, Anubias, and moss balls. For more demanding plants, choose a tank with full-spectrum LEDs and consider adding a plant-specific light.
What size tank do I need for a betta fish?
Bettas need at least 2.5 gallons, but 5 gallons is ideal. The Marineland Portrait and Koller 5-gallon kits are excellent choices. Avoid bowls or tiny tanks under 1 gallon, as they cannot maintain water quality.
Do I need a heater for my aquarium?
Most tropical fish require a stable temperature between 74-82°F, so a heater is essential unless you keep coldwater species like goldfish. Many starter kits do not include a heater, so check the product details. Visit our Fish & Aquariums section for more tips.
