Rimless Aquarium Advantages

Finding the perfect rimless fish tank for sale can be a challenge.

But with this guide, hopefully your search has ended!

Most pet stores don’t carry these.

And if you’re someone who wants your tank to do more than just hold water and fish but actually be a living work of art…

… You’ve come to the right place.

Rimless tanks are undoubtably a cut above the rest in terms of aesthetics.

Most people are shocked at the difference not having that distracting trim can make!

(Hint: it’s not recommended to do that if you already have a tank that comes with a brace, or you can risk having it explode without that frame to support it.)

Now the focus is on what’s INSIDE the aquarium rather than what’s all around it.

Your aquatic masterpiece becomes more striking than ever before.

It doesn’t matter where you want to put it – it looks good everywhere!

Instead of being an eyesore, the tank becomes a decorative focal point.

Look:

There’s a reason the professional aquascapers go with rimless tanks.

And now you can make one yours.

Which Size and Shape is Best?

That’s an important question to ask when it comes to picking out the tank.

There are two main styles: upright and horizontal.

There are also square cube designs, which can add a contemporary flare.

But ultimately the shape you choose comes down to what fits the space best where you would like to place the aquarium.

Smaller tanks are great for an office or nightstand where room is an issue.

Bigger tanks can support more fish and reduce maintenance (depending on various factors such as stocking density, filtration etc.).

Ultimately it comes down to what works best for the species and number of fish you intend to house.

Speaking of filtration…

Filtering a Rimless Tank

So you go to all the trouble to banish that ugly black trim, but then you have big black hideous filter inside the tank making you sad.

What do you do?

Concealing your filtration can be done.

For larger tanks:

The professionals like to use glass lily pipes connected by clear tubing to canister filters, concealed underneath the aquarium’s cabinet.

These are usually positioned on the side of the aquarium, rather than on the back so that face-on they won’t get in the way.

Smaller tanks can be trickier.

Undergravel filters are probably the most inconspicuous, but not everyone wants to use gravel.

Having a black background can come in useful for concealing filtration, but not everyone wants black.

If you’re like me, you might consider heavily planting the tank and lightly stocking it as to remove the need for an electric filter altogether.

Or you might just try to hide the filter behind some plants or rocks, which can work quite well depending on the setup.

But to each their own 🙂
