5 Best 10 Gallon Fish Tanks for Beginners and Experts 2019

It used to be that all fish tanks were basically the same: a large rectangle with a black lid. If you wanted to get fancy, you might even be able to find a tank with a faux-wood lid.

But all that has changed. Now there are so many different tank designs and filter types out there that choosing your next tank can be a bit of a challenge.

If you’re looking for a new 10-gallon tank, we have some tips for you as well as our picks for the best 10-gallon fish tanks. Whether you’re new to fishkeeping or a seasoned aquarist, you’re going to want to keep reading.

Is a 10-Gallon Tank the Right Choice for Your Needs?

10-gallon tanks have always been the perfect starter tanks for new fish owners, but they’re also great choices for seasoned fish keepers looking to start a specialty or brooding tank. But, before you set your sights on this sized tank, it’s worth taking a moment to make sure its the right size for your needs.

Number of Fish

The standard rule for the number of fish in a tank is one inch per gallon. But that doesn’t necessarily mean a 10-gallon tank can hold 10 fish.

Fish vary in size by species and age. Always take into account the size your fish will be when fully grown when calculating how many fish you can fit.

When measuring your fish, look at the approximate size of their body (not including the tail). Most popular tropical fish like tetras tend to be about an inch each, while goldfish can vary greatly in size and you often won’t know how big they’ll be until after you purchase them.

Spruce Pets recommends also taking into account the amount of space taken up by decor and plants. Your 10-gallon tank is likely to only hold 8 or 9 gallons of water after you factor in rocks, filters, and decorations.


Unlike a fishbowl, which can be easily scrubbed clean while your fish hang out in a temporary container, a 10-gallon tank requires regular upkeep.

Fishkeeping World recommends weekly checks of the water’s PH and ammonia levels and a partial water change every 2 to 3 weeks. For this degree of maintenance, you’ll need special test strips for water purity as well as an aquarium vacuum and chlorine-free water.

You’ll also need to clean and replace your filters routinely and scrub algae from the glass as needed.

Of course, all this care is worth it if you have the time for it.

Tanks offer a lot of advantages over fishbowls. They are much larger, allowing for more decorations and fish and you can keep an endless variety of freshwater, tropical, or saltwater fish while a bowl is limited to only a few species that can gulp air directly from the atmosphere.

Understanding Different Filter Types

One aspect of selecting a new tank that shouldn’t be overlooked is the filter type. Many tank kits come with all major accessories included, and while your attention may be fixed on the look of the tank design, taking a moment to understand the pros and cons of what kind of filter you’re getting is important in assuring you don’t regret your decision later on.

“Hang On” Filters

This is the most common filter type used in beginner and intermediate fish tank kits. This filter sits on the back or side of the aquarium and a siphon pulls water up through the filter pathway.

A multilayer filter piece typically provides large debris skimming by catching items in a floss screen while the filtration of chemicals is accomplished through a carbon filter. The filter cartridge allows beneficial bacteria to grow which further cleans the water.

These filters are simple to use and clean but aren’t as powerful as other options. They also can be a little noisy, especially if you don’t like the sound of trickling water.

Undergravel Filters

These types of filters used to be more common and can still be found in more expensive 10-gallon tank kits. Instead of relying on a single siphon to pull water from the tank at about mid-level, these filters have tubes that open under a strainer that sits beneath the gravel.

The water is pulled through an air pump or a similar mechanism and pushed back into the tank, helping oxygenate the environment. There is no chemical filter with this set up which means, while the water may stay clearer for longer, ammonia can still build up in the system, especially near the bottom of the tank.

These filters are easier to upkeep than others since they have no filter pads to replace and the system itself stays relatively clean. But you will have to clean your gravel much more often and do more partial water changes to keep a healthy PH.

Internal Filters

These types of filters are similar to hang on filters but are much more compact and use suction cups to attach to an inside wall of the tank. While these would not be sufficient to clean a large tank, they do work well for 10-gallon tanks.

These filters can remove sediment from the water before it has time to settle on the bottom of the tank and usually come with filter pads that contain chemical and biological filtration similar to hang on filters.

The best internal filters have air pumps that help push water through the system and oxygenate the tank. These filters are quieter than the other two options but not quite as powerful, especially for tanks that produce a lot of waste.

This tank even comes with a remote to create custom light color blends and activate special effects options.

Low capacity filter

If you’re looking for a tank with a clean design and an ultra-clear view of your school, the Hygger Horizon 8-Gallon tank is an excellent choice.

The sleek design of the aquarium uses a curved front panel similar to our second choice pick but also incorporates a clear top panel for an uninterrupted view of the environment inside.

This tank comes with a built-in faux rock 3D back panel that allows crevices for the fish to hide in while also hiding the filtration system. Unfortunately, this bulky feature reduces the true capacity of this tank to only 6 gallons.

The filter is an internal system that is ultra-quiet but has a lower capacity than others on the list. But, this system has the unique distinction of functioning even when the water level in the tank is below half-way, a great feature for beginner aquarists or kids who might occasionally forget to refill the tank when needed.

Like our third pick, this tank comes with a remote and multicolored lights for extra customization.

Given the low capacity and limited features, this tank is a little higher priced than you might expect, but the unique design and clean look are worth the extra investment.

What happens if a tank is too crowded?

You don’t want to remove more than 50% of the water during any one cleaning or else you risk throwing off the balance of beneficial bacteria and overwhelming your fish with water of a dramatically different PH and temperature.
