Advantages of rimless aquariums

Finding the perfect rimless fish tank for sale can be a challenge. In fact it’s not hard to find these rimless aquariums out of stock. But with this guide, we hope your search is over!

Most pet stores do not carry this. And if you’re someone who wants their tank to do more than just hold water and fish, but to be a living work of art, you’ve come to the right place.

Rimless aquariums are undoubtedly a level above the rest in terms of aesthetics.

Most people are surprised at what a difference not having that distracting frame can make. It is not recommended to remove the frame if you already have a tank that comes with one, or you may risk it exploding without that frame to support it.

Now the focus is on what is INSIDE the aquarium instead of what is around it. Your aquatic masterpiece becomes more eye-catching than ever.

No matter where you want to put it – it looks good everywhere!

What size and shape is the best?

That is an important question to ask when it comes to choosing the tank. There are two main styles: vertical and horizontal. There are also square cube designs, which can add a contemporary touch.

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

The smaller tanks are ideal for an office or nightstand where space is an issue.

Larger tanks can support more fish and lower 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 intended to be housed.

Speaking of filtration…

Filtering a rimless tank

So you go to all the trouble to banish that ugly black clipping, but then you have a horrible big black filter inside the tank that makes you sad.

What are you doing? Hiding your leak can be done.

For larger tanks, professionals like to use glass tubing connected by clear tubing to canister filters, hidden under the aquarium cabinet.

They are usually placed on the side of the aquarium, rather than at the bottom, so they are out of the way.

Smaller tanks can be more difficult. Gravel filters are probably the most inconspicuous, but not everyone wants to use gravel. Having a black background can be helpful in hiding the leak, but not everyone wants black.

If you’re like me, you might consider putting aquarium plants in the tank and populating it slightly to eliminate the need for an electric filter altogether.

Or you could try hiding the filter behind some plants or rocks, which can work quite well depending on your setup.

But to each his own
