Best Rimless Aquarium Buying Guide

Rimless aquariums are usually made of either acrylic or glass, and they do not have any frame or rim around the structure, thus being named rimless.  The joints might be glued up or mitered, or could be beveled or rounded as well.

They are really good for a clear all-round view, and as they look beautiful, they are perfect for decorations. So how would you choose the best rimless aquarium for your bedroom or office lobby? This buying guide will walk you through.


Choose between glass or acrylic builds, but remember, both have their merits and demerits. Glass is scratch-resistant, more durable, but could have sharp edges. They are also heavier, more expensive, land et’s not forgotten the fact that that they are not highly impact resistant.

On the other hand, acrylic constructions are more light-weight, do not break or shatter upon impact, quite durable, but on the sadder note, they are not that resistant to scratches.

You can walk by and a light touch of a sharp object like your bracelet, may leave a permanent scratch mark on the surface of your newly bought acrylic rimless fish tank. If you decide to go for acrylic manufactures, then also get the appropriate cleaning tools available so that while cleaning you do not leave any scratch or dent.

Another thing to note here is that glass aquariums do not need a support to stand on, whereas acrylic ones do. If acrylic aquariums are kept without a support, like a cabinet, the weight of the water may cause the lower part to get detached as time progresses.


Size matters when you have a smaller house or do not stay at home much, or you stay busy most of the time. Larger aquariums need a larger space to be placed in or against, and unless you have sufficient space inside your house to keep one, it is a better idea not to go for medium or large sized aquariums.

Also larger the fish tank, the higher the maintenance, therefore if you stay busy or out most of the time, there is a high chance for your tank to get dirty. So think before you leap.
