FAQs :::

What’s the difference between rimless tanks and traditional tanks?

Rimless aquariums do not use metal rims in the construction of the tank. These tanks are made out of thicker glass or acrylic material and have silicone seams to prevent bowing and spillage. They look like a floating cube of glass rather than a traditional tank.

Should I buy a glass or acrylic aquarium?

It’s personal preference! Glass tanks are heavier, but more easily cracked. Acrylic tanks refract light less, so you can see what’s in the water more clearly. However, they do yellow over time, and glass doesn’t. Acrylic tanks scratch much easier as well.

Where does the filter, heater and light go?

Because of the growing popularity of rimless tanks, many manufacturers offer lights, filters and heaters that clip right on to the side of the tank or hang off the back. They really do not deter from the clean look of the tank.

Will my fish stay in the tank?

Many rimless fish tanks don’t come with lids, which is an issue if you have fish prone to jumping. You can easily make a lid by purchasing hinges and a piece of hard plastic from your local hardware store.

Do rimless tanks only come in small sizes?

No! Rimless tanks can hold three gallons or 180 gallons or even more! The size of the tank is dependent on the quality of construction of the fish tank. Rimless tanks are typically made of thicker glass or acrylic to bear the weight of the water inside the tank. So, the larger the tank, usually the thicker the glass you’ll see. Additionally, you want to make sure that the tank is held together evenly at the edges with high quality silicone.

Do rimless fish tanks only come in cube or square sizes?

If you’re looking to purchase a rimless tank in glass, you’re most likely going to find only square or rectangular shapes. Glass is pretty rigid and brittle, making it hard to bend. When glass is curved, it also can distort the view of what is inside the aquarium because it bends light, making the fish inside of the tank look smaller than they are. You will however, find some rimless tanks, like the ones we have listed above, with curved edges. However, acrylic tanks can be found in a wide variety of shapes because they are so easily malleable and because they don’t really distort the images that you see through it when it is curved.

Do I have to buy a stand to put this rimless tank on?

It depends on what kind of aquarium that you buy. Most glass aquariums are strong enough that they can stand alone on a shelf, a desk, or a level stand that you purchase to go along with the tank. However, because glass tanks are much heavier than their acrylic counterparts, you need to make sure the stand is strong enough to support the weight of the tank with water in it. Herein lies the difference with some acrylic tanks. If you purchase an acrylic aquarium that does not have a very thick bottom, it is very important that you purchase a tank to have a stand or a foam mat to support the bottom of the tank. Without a stand, it’s very possible the bottom of the tank could separate at the seams from the rest of the tank, spilling the contents of your tank all over.

Which is more expensive, a glass or acrylic tank?

Rimless aquariums don’t have to be expensive! You can get some smaller rimless tanks for under $30, but if you’re going to get a tank that’s larger than 3-4 gallons, it’s likely going to cost around $50 or more. That being said, glass tanks are typically less expensive than acrylic fish tanks. Glass tanks are slightly easier to make, requiring less specialized tools to create. Acrylic tanks tend to be more expensive because of that, but of course that doesn’t necessarily mean they are better! It is important to fully read all reviews and manufacturer specifications before making a purchase to know that you are getting the best quality tank.

Can I trust buying a rimless tank online? Won’t it show up broken?

Sellers have gotten very good at packaging fish tanks of all sizes to make sure that they get to you in pristine condition. You’ll often find them wrapped in layers upon layers of bubble wrap and shipped in a large wooden crate to ensure that they are not broken or damaged in shipping. You have a higher risk of receiving a broken or cracked rimless aquarium if you purchase it in glass, however, acrylic tanks are so easily scratched, people often report that they have to ship a number of tanks back and forth from the seller before they get one that is in mint condition. You also might see sellers charging a shipping AND handling fee, so be prepared to pay extra. Buying online is not always a cheaper option.

What happens when someone knocks into my rimless tank by accident? Won’t I lose everything?

Not necessarily. If you opt for a tank that is rimless, you probably can expect some water to slosh out of the tank. Depending on how high your water level is, or how close your fish is to the surface, you definitely could see them fly out. This is why some people choose to put a layer of clear netting over the top of their tank, even if they don’t want to put a lid on their tank. If someone or something knocks into your acrylic tank, your main risk is losing water or the fish tank being overturned. They could also break apart at the seams. It would take a very strong impact for your acrylic tank to be shattered or cracked. However, rimless glass tanks have the potential to shatter or crack, even if they’re made out of tempered glass. It is best to make sure you place your tank in a secure place in your home, if possible.
