27 Small Fish Tank Ideas – Complement Your Home

A beautifully decorated aquarium full of glittering Rosy barbs, elegant Angelfish, and shoals of sparkling Neon tetras makes a stunning centerpiece in any home.

The smallest apartment or compact bachelor pad can enjoy the relaxing, health-giving  presence of a few fish, even if there’s only space for a small fish tank.

Bigger is Better

When choosing a fish tank, you must always consider the individual fish’s requirements in terms of quality of life. Before buying a tank, research the correct tank size for your fish.

As a general rule of thumb, you need one gallon of water per inch of fish. Tiny tanks often lack filtration systems and heaters, which can lead to polluted, chilly water conditions that stress the fish. Stressed fish are more susceptible to diseases and will fail to thrive.

Bottom line: a bigger tank is better for your fish.

This cleverly designed piece of chic home décor is a planter and a fish tank. You place a potted plant inside the top of the unit and keep your fishy friend below.

The fish waste provides the plant with nutrients, and the water that you give to the plant passes through a filter to produce clean water for the fish. The water stays crystal clear and free from ammonia and nitrates, and the pH level remains stable. Genius!

Now that most of us have iPhones, the payphone is somewhat redundant.

In Japan, the art collective Kingyobu has repurposed several public phone booths to create street aquariums containing hundreds of goldfish.

Kingyobu, which translates roughly as “goldfish club,” is responsible for the project in Osaka. In Japan, the goldfish is a symbol of prosperity and happiness, and the public loves the idea of passing these living good luck charms on their daily commute to work.

This amazing “glasscape” fishbowl was designed and created by New York-based company, Aruliden.

The bowl is traditional on the outside but has a stunning, mountainous landscape interior detail. When you add water to the bowl, the refraction created by the light transforms the picture by accentuating the topographical sculpture.

Here’s another variation of the coffee table fish tank, this time created from glass.

The square unit is designed to show off your fish collection from all angles, as well as being a practical, functional, and eclectic piece of furniture. I love the idea of making maximum use of the space you have available by combining the best of both worlds.

Also, unlike some tiny tank ideas, the coffee table aquarium has filtration, heating, and lighting, creating the perfect, healthy environment for the fish.

The main drawback of this style of tank is that you need to cover the lighting, heating, and filtration cables underneath a rug or carpet.

The USB-powered, self-cleaning tank comes complete with a running water pump and sponge filter medium to keep the water clean and clear. The capacity of the tank is only around half a gallon, so it’s only suitable for small invertebrates such as shrimp and snails or perhaps a couple of small tetras.

18. iPond

A TINY fish tank that doubles as a music speaker

This super-tiny fish tank sparked controversy among hobbyists and animal rights groups when it was released in the run-up to Christmas in Australia back in 2007.

The brick-shaped tank doubles as a music speaker and its novelty value saw high sales of the item. However, although the idea is cute, I do not advocate using one of these. The unit is far too small for even the tiniest fish to live in, and there’s no filter to keep the water sanitary.

That said, a decorative fish model made from enamel or glass would look great inside the unit without being cruel to a living creature.


19. Wall-Mounted Aquarium

If you don’t have space for a traditional fish tank in your home, a wall-mounted aquarium could be the solution.

The aquarium looks just like television but is actually a fish tank! The unit is only 4.5-inches deep but can still accommodate an ocean or tropical aquascape with ease. A wall-mounted aquarium is a brilliant space-saving idea that’s also a guaranteed conversation piece. Even celebs such as Stephen Spielberg have them!

The aquarium comes supplied with mounting brackets and associated hardware, as well as a bio and charcoal filtration system, siphon cleaner, a fishnet, marine background, lid, LED light fixture, and grabber tongs.

Basically, the item does what it says on the tin. This is an acrylic fishbowl that’s designed to fit into a flat carrying case with a handle, enabling you to transport your fish safely when needed.


21. DIY Portable Aquarium

This idea for a full-size portable aquarium that you can make at home could be a really useful, practical solution for students who want to take their fishy friends with them to college.

The tank is made from seamless plastic, allowing you to lift the unit while it still contains water. Having moved home a few times, I can appreciate the convenience offered by this tank. You can’t lift a regular glass tank and its contents because the weight causes the seals on the corners to warp. The strain may also cause the glass to crack- disaster!

This neat project can be completed for under $5.

25. Jellyfish Round Lamp

Bambus LED Fantasy Jellyfish Lamp Round with 5 Color Changing Light Effects, Electric Jellyfish Tank Table Lamp with Color Changing Light Gift for Kids Men Women Home Deco

I included this item in my list because it looks great, even though it’s not strictly an aquarium.

The jellyfish inside the lamp are artificial, so you don’t need to worry about caring for them. The high-quality UV lamp comes with a full three-year guarantee, which is always good to know.

The lamp is designed to act as a nightlight and a portable UV cellphone sanitizer. Complete with different color changing light effects, this makes a wonderful mood light for a kid’s bedroom that won’t disturb their sleep and has health benefits too.

Even if you live in a small place, you can still enjoy the relaxing sight of a few small fish or a beautiful betta by choosing a small fish tank.

When choosing a small fish tank, you must always consider the individual fish’s requirements in terms of quality of life. The items in this list are purely to inspire you to get creative, but your pet’s welfare should always be your top priority.
