60 Gallon Cube Fish Tank – The Ultimate Guide To Planning, Stocking
Every aquarist knows the feeling of staring at a blank glass box and imagining a thriving underwater world. You want something that stands out, but perhaps a standard 4-foot long tank doesn’t fit your living room layout.
We’ve all been there—struggling to find that perfect balance between a significant water volume and a compact footprint. It can be frustrating to feel limited by floor space when you want to keep a diverse range of species.
Don’t worry—this setup is perfect for beginners and intermediate keepers alike! In this guide, I will walk you through everything you need to know about setting up a 60 gallon cube fish tank, from choosing the right gear to selecting the perfect inhabitants.
By the time you finish reading, you’ll have a clear roadmap to creating a stunning vertical masterpiece. Let’s dive into the specifics of why this unique shape is a game-changer for your home aquarium.
Why Choose a 60 Gallon Cube Fish Tank?
The most immediate draw of this setup is the aesthetic appeal. Most standard tanks are horizontal rectangles, but a cube offers a deep, 3D perspective that draws the eye in.
A 60 gallon cube fish tank typically measures roughly 24x24x24 inches. This symmetry creates a “diorama” effect, allowing you to create layers of hardscape that aren’t possible in shallower tanks.
Because the footprint is smaller than a standard 55-gallon or 75-gallon tank, it fits perfectly in corners or as a standalone “island” feature. It provides a massive amount of water volume without taking up an entire wall.
Essential Equipment for Deep Cube Aquariums
When dealing with a cube, you have to think differently about equipment. Standard “hang on back” filters might not reach the bottom corners, and light has to travel through 24 inches of water.
To keep your 60 gallon cube fish tank healthy, you need to prioritize penetration and circulation. Let’s look at the core components you’ll need to get started.
High-Performance Filtration
In a cube, water tends to “vortex” or leave “dead spots” in the bottom corners. I highly recommend using a high-quality canister filter like the Fluval 407 or an Oase BioMaster 600.
These filters allow you to place the intake and output in specific locations to ensure total turnover. You want a filter that moves at least 300 to 400 gallons per hour (GPH) to keep the water crystal clear.
Lighting for Depth
Standard shop lights won’t work here. Since the tank is 24 inches deep, low-end LEDs will lose their intensity before reaching your substrate.
If you plan on growing plants, look for high-PAR LED fixtures like the Kessil A360X or the AI Prime Fresh Water. These “pendant” style lights are perfect for cubes because they provide a beautiful shimmering effect and can punch through deep water.
Heating and Circulation
A single 200W or 300W heater is usually sufficient. However, because heat rises, the bottom of a tall tank can sometimes stay cooler than the top.
To fix this, I always suggest adding a small wavemaker or circulation pump. Placing a small powerhead near the bottom helps push warm, oxygenated water into every corner of the glass.
Hardscaping Strategies: Mastering Vertical Space
One of the biggest mistakes hobbyists make with a 60 gallon cube fish tank is “flat landscaping.” If all your rocks and wood are at the bottom, the top two-thirds of the tank look empty and cavernous.
To create a professional look, you must utilize the verticality of the aquarium. This is where your creativity can really shine through hardscape selection.
Using Manzanita and Spider Wood
Long, spindly branches like Spider Wood are perfect for cube tanks. You can position them so they reach from the substrate all the way to the water’s surface.
This provides “high-rise” real estate for your fish and places for epiphytic plants like Anubias or Java Fern to grow mid-water. It breaks up the line of sight and makes the tank feel much larger than it is.
Creating Rock Pillars
Instead of a long wall of rocks, try building a central “island” or a tall pillar using Seiryu Stone or Dragon Stone. Use aquarium-safe epoxy to stack stones securely.
A tall central structure allows fish to swim 360 degrees around the hardscape. This creates a more natural environment and encourages active behavior in schooling species.
Substrate Depth and Sloping
I like to slope the substrate from the front to the back. In a cube, having 4-5 inches of substrate at the rear and only 1-2 inches at the front adds incredible depth.
This technique, often used by professional aquascapers, tricks the eye into thinking the tank is much deeper than 24 inches. It also provides plenty of room for heavy-rooting plants.
Best Fish and Invertebrates for Cube Setups
Stocking a 60 gallon cube fish tank is an absolute joy. Because you have so much vertical space, you can choose fish that occupy different “strata” or levels of the water column.
You aren’t just limited to “long swimmers”; you can house species that appreciate height and slow-moving water. Here are some of my favorite stocking ideas for this specific footprint.
The Majestic Angelfish
Angelfish are the “kings” of the cube tank. Their tall, disc-shaped bodies are evolutionarily designed for vertical environments.
In a 60-gallon cube, a bonded pair of Angelfish makes a stunning centerpiece. They will utilize the entire height of the tank, gracefully weaving through tall plants and wood.
Schooling Species for Middle Layers
To add movement, consider a large school of Rummy Nose Tetras or Cardinal Tetras. A group of 20-30 of these fish looks breathtaking as they move together through the center of the cube.
The contrast of a tight-knit school against a tall hardscape provides a sense of scale. It makes the aquarium feel like a genuine slice of a tropical river.
Bottom Dwellers and Clean-up Crew
For the substrate level, you can’t go wrong with Corydoras Catfish. A group of 6 to 10 Sterbai Corys will keep the bottom turned over and add a lot of personality.
Don’t forget the invertebrates! Amano Shrimp and Nerite Snails are essential for keeping algae off your tall glass walls and intricate hardscape.
Choosing the Right Aquatic Plants
Plants are the lungs of your aquarium, but in a cube, you have to choose species that can handle the height. Some plants will grow toward the light, while others prefer the shaded areas under wood.
Tall Background Plants
For the back corners, I recommend Vallisneria Americana or Amazon Swords. These plants grow very tall—often reaching the surface and “curling” over.
This provides a lush, green curtain that hides your heater and filter pipes. It also gives shy fish a place to retreat and feel secure.
Mid-Ground and Epiphytes
Since you likely have wood reaching into the middle of the tank, use Bucephalandra and Anubias Nana Petite. You can wedge these into the crevices of your wood or rocks.
These plants don’t need to be buried in the substrate. They take their nutrients directly from the water column, making them perfect for “vertical gardening.”
Foreground Carpeting
If you have strong enough lighting, a carpet of Dwarf Hairgrass or Monte Carlo looks incredible. However, remember that maintenance at the bottom of a 24-inch tank can be a bit of a reach!
If you prefer something easier, a simple layer of cosmetic sand with some Cryptocoryne Parva can give you a beautiful, low-maintenance foreground.
Maintenance Tips for Tall Glass
Maintaining a 60 gallon cube fish tank presents a few physical challenges, primarily due to the depth. You’ll need to adjust your toolkit to keep things running smoothly.
The most important tool you will buy is a long-reach algae scraper. Unless you have very long arms, reaching the bottom back corners with a sponge is nearly impossible without getting your shoulders wet.
Managing Water Changes
I recommend using a Python No-Spill Clean and Fill system. Dragging buckets of water for a 60-gallon tank is a recipe for a sore back.
When vacuuming the substrate, be careful not to topple any tall rock structures. Because of the height, gravity works against you if a stone becomes loose.
Trimming and Pruning
Invest in a set of extra-long aquascaping scissors (12 inches or longer). This allows you to prune your tall background plants without having to submerge your entire arm.
Regular trimming is vital in a cube. Because the footprint is compact, fast-growing plants can quickly “choke out” the light for the species living at the bottom.
Frequently Asked Questions
Is a 60 gallon cube fish tank too heavy for a standard floor?
A filled 60-gallon aquarium, including substrate and rocks, can weigh over 600 pounds. Most modern homes can handle this weight easily, especially if placed against a load-bearing wall. However, always ensure your aquarium stand is specifically rated for this volume.
Can I keep Discus in a 60-gallon cube?
While a 60-gallon cube provides the height Discus love, it is on the smaller side for a group of adults. If you are an experienced keeper, a pair could work, but for a group, a larger horizontal tank is generally preferred for better swimming room.
How do I prevent “dead spots” in the corners?
As mentioned earlier, use a circulation pump. Position it so it pushes water across the back glass. This ensures that debris doesn’t settle in the corners and that oxygen is evenly distributed.
Do I need a glass lid for a cube tank?
Yes, I highly recommend a glass canopy. The high surface area of a cube can lead to significant evaporation. A lid also prevents “jumpers” like Hatchetfish or certain Tetras from ending up on your floor.
Is it harder to clean a cube than a rectangular tank?
It’s not necessarily harder, but it is deeper. You will need longer tools and a bit more patience when reaching for items that fall to the bottom.
Conclusion
Setting up a 60 gallon cube fish tank is one of the most rewarding projects an aquarist can undertake. It challenges you to think vertically and offers a unique viewing experience that long tanks simply cannot replicate.
By focusing on powerful filtration, deep-reaching light, and a tall hardscape, you can create an underwater forest that will be the focal point of any room. Remember to choose fish that appreciate the height, and don’t be afraid to get creative with your planting.
Whether you are looking to house a pair of elegant Angelfish or a massive school of shimmering Tetras, the cube format provides the perfect canvas. Happy fish keeping, and enjoy the process of building your new aquatic masterpiece!
