The 6 Best Self-Cleaning Goldfish Tanks

1. AquaSprouts Garden Self-Sustaining Desktop Aquaponics – Best Overall

The best overall self-cleaning tank for goldfish is the AquaSprouts desktop aquaponics ecosystem. This is a 10-gallon tank that has a tray at the top where you can grow plants. Although it is labeled as a desktop aquarium, it is too large to comfortably fit on many desks.

The provided planting space allows you to grow a variety of different herbs or small plants that will absorb ammonia and nitrates from inside the aquarium to help keep it cleaner for the goldfish.

The design is quite attractive and looks simple, and it works by reducing the number of water changes and filter cartridge replacements you need to do. Since it's small, you will only be able to keep one to two tiny goldfish inside and upgrade their aquarium as they grow.

2. Huamuyu Hydroponic Garden Aquaponics Fish Tank – Best Value

When it comes to an affordable self-cleaning tank, the Huamuyu hydroponic fish tank is the best value for money. This small tank includes an innovative and modern design that makes it the perfect desktop aquarium that you can enjoy on your desk while you work or study.

It comes with a water pump, plant growing medium, and a tray at the top where you can grow small edible plants or even houseplants. The plants act as a filtration system for the goldfish tank by pumping the water from the aquarium where the plants absorb the waste produced by the goldfish which is then poured back out through the filtering system.

Since it is such a small tank, we do not recommend housing goldfish in here long term. It can be used as a short-term housing tank for one baby goldfish.

3. ECO-Cycle Indoor Aquaponics Garden System – Premium Choice

Our premium choice is the ECO-Cycle indoor aquaponics garden system. This is an excellent self-cleaning tank for goldfish because it is much larger in comparison to other similar tanks that we have reviewed. This tank can hold 20 gallons of water, which makes it suitable for two small baby goldfish.

The design itself is unique and the perfect example of a good self-cleaning tank using a garden system. The planting tray at the top allows you to grow a variety of plants such as herbs that help to keep the water clean. The LED grow light at the top of the tank is strong enough to grow your plants from seeds, and you can use a remote control to choose from four different grow settings with the addition of a timer.

4. Springworks Microfarm Aquaponics Garden Fish Tank

The Springworks microfarm aquaponics garden fish tank is a low-maintenance 10-gallon fish tank that works by self-cleaning through an aquaponics system. This fish tank includes a light for plant growth and has a modern rectangular design that makes it easy to grow plants that absorb the nutrients from the fish water and in return flows the clean water back into the goldfish tank.

It also comes with a pump and organic oregano seeds that you can plant in the top part of the tank.

With this size tank, you will be able to fit one small goldfish inside.

5. Back To The Roots Indoor Aquaponic Fish Tank

The Back to the Roots aquaponic fish tank is a small and low-maintenance 3-gallon aquarium. It is convenient and easy to set up and use to grow a variety of herbs, houseplants, and microgreens while also helping to keep the water for fish clean.

The goldfish waste is used as a fertilizer for the plants and then it is returned to the aquarium with the waste removed, greatly reducing the need for water changes. The pump that is installed in this system that sucks the water up to the plant's growth bed can be quite strong, so blocking it with a rock or heavy ornament can help prevent injuries to your goldfish.  A bonus to this fish tank is that it includes a silent water pump, grow stones, gravel, fish food, and different plant seeds to get you started.

Since it is a small size, this tank can be used as a temporary viewing tank for a small baby goldfish, as it is not big enough to house a goldfish long term.

6. Daxiga Hydroponics Growing System

The Daxiga hydroponics growing system fish tank is an aesthetically pleasing self-sustainable fish tank that functions as a fun and practical way to grow small herbs and houseplants while keeping fish. This self-cleaning tank comes with a variety of products that make it worth the price, such as a control and display panel, an LED light, a plant cover, and a water pump.

It makes it easy to grow plants and herbs using the growth light set up with a timer, along with a water circulation system that benefits both the fish and the plants you are growing. It also looks good, and it can be placed on a kitchen countertop or a desk.

It is on the smaller side with a volume of only 3 gallons, so it is not the best long-term housing for goldfish.

Buyer’s Guide: Buying the Best Self-Cleaning Goldfish Tanks

How Does a Self-Cleaning Goldfish Tank Work?

Self-cleaning fish tanks are an innovation that allows provides a self-sustainable ecosystem from the combination of plants and fish. When the fish excrete waste into the water, it is pumped up into the plant's growth medium where the plants absorb the ammonia and nitrate from the water to use it as a fertilizer.

The clean water is then passed through a filter and pumped back into the fish tank to create a cleaning cycle. Reducing the number of water changes you will need to do throughout the month can be great for those who want to own fish but do not want to lug a heavy bucket around.

What To Consider Before Keeping Goldfish in a Self-Cleaning Tank

If you are familiar with goldfish, you will know how messy these fish can be and how large of an aquarium they need. When goldfish are kept in smaller tanks, the water can become dirty quickly, and you will need to do more tank maintenance. However, when kept in a large aquarium with a good quality filter and a decent stock of goldfish in the tank, you will not have to do much cleaning.

Once a tank is cycled and set up appropriately for goldfish, the beneficial bacteria in the aquarium will do most of the ammonia to nitrate converting, and live plants will absorb excess nitrates and ammonia in the water. Self-cleaning fish tanks are mainly for convenience and to make a mini-indoor aquaponic system that you can keep on small surfaces and grow small plants.

Most of these self-cleaning tanks are too small for goldfish and can be more work in the long run than if you were to buy the correct tank and equipment for the goldfish.
