Mr. Aqua Frameless Aquariums

Mr. Aqua aquariums are produced using high clarity glass with thicknesses ranging between 5mm to 10mm depending on the size. By eliminating the plastic frame that surrounds typical aquarium systems, the Mr. Aqua aquarium provides a clean and clear view of your aquatic life.

Normally the plastic frame is used to support and keep the glass from bending under pressure in standard quality aquariums. Mr. Aqua utilizes a thicker glass for increased rigidity with a specially formulated silicone manufactured in Germany that bonds the glass together with extreme strength while being safe for your fish and aquatic life.

Each glass aquarium is meticulously assembled with straight and true beveled cut glass and a fine application of high strength silicone, making the Mr Aqua aquarium not only watertight and rigid but aesthetically pleasing to the eyes.**

Mr. Aqua offers a wide ranges of sizes to accommodate any aquatic layout, providing a zero compromise solution for your aquatic layout.


  • Dimension: 35.4" x 8.3" x 9.4"
  • 12 Gallons
  • Extra fine silicone finish

*All panels are constructed of non-tempered glass
** Aquarium must be placed on a solid surface that can support the weight of the aquarium. A leveling mat (Mr. Aqua Hybrid Foam Mat, or a yoga mat) is required.

Great, non-cube 1.5 gallon

I prefer the landscape shape of tanks vs cube style. This is the smallest one I've found and it's awesome! The silicone job on the bottom inside could've been better, but it will be covered by substrate anyway. For the price, it's very good! I'm happy with my purchase.

planted 12 gal tank

My first tank was fluval 12 gal tank which was horrible. I wanted to have a planted tank ( dirt), and so I went with the 12 gal tank (36 inch x 8 x 9. I have a 36 inch current led light which fits perfectly, and a epheim canister fliter. The light is bright ( since the tank is so shallow, the plants are growing so much better, and the neons have room to actually swim in a school. I really love this tank ( I got the low Iron glass and painted the back of the tank black)

Excellent Tanks

The size of this tank is excellent. May only be 6 gallons but with the way it is made fish have lots of room to swim. The quality is excellent. Service is great. So pleased have another of Mr. Aqua tanks on the way.

12 gallon looooooong

I have been wanting this long low beauty for 2 years now and I am glad to have taken the plunge. The vast area of plantable area combined with the low height, allowing much more light to get to the leaves and also allowing taller plants to punch right on out to the air, make this an ideal planted tank for me. Of course, make sure to get twice as much substrate as you would for a 10 gallon to cover all that space. I plan to use an ehiem Ecco with inlet on the opposite end of this long tank to get a lengthwise flow going and avoid the eyesore that a HOB can be. I love that a 36" LED fits this 12 gallon perfectly for an open top water garden and easy access for tinkering. Glass clarity is good, although a purist will likely want to upgrade to the low iron. Th bottom is much thicker than I imagined, I assume this is where this tank gets it's strength to go frameless. Silicone is very clear, but a little sloppy on the bottom. The substrate will cover that just fine. Silicone on the sides is very nicely done. First shipment was packed amazingly well, but still managed to arrive broken. Marine warehouse sent a replacement the same day and the second arrived in great shape. Fast and friendly service. Recommended.

Great tank!

I love this tank. It looks great, I have it divided for 4 betta. One star off because evaporation is an issue and it's hard to find appropriate lighting and a cover at an affordable price. Packaging for shipping was excellent. Delivery time short. Would definitely get a second one if I had space. the Mr. Aqua label was peeling a bit but that doesn't bother me. I get what people say about the silicone, but unless you're entering this into some kind of perfect tank competition, it's hardly noticeable. I used 3/4 of a 25lb bag of gravel, so it does use a lot. I'm using the tetra whisper filter and it fits, but just barely. I really love how my tank came out overall and highly recommend.

Cool Tank!

I like this tank a lot, it looks like a scaled down 125 gal that takes just a little more space than two five gal tanks. I'm using it for a swordtail grow out tank, perfect for that, the length gives them lots of swimming room so they grow well before being moved to a larger tank. They can stay in this tank a few weeks longer than a shorter one, too. Nice!

Beautiful Tank

The tank arrived on time and in very good condition. Very well packaged. The only reason I gave 4 instead of 5 stars is that the thermometer was bubble wrapped except for the end that opens and as luck would have it the container opened and the thermometer escaped and broke. A simple piece of scotch tape over the end could avoid future incidents like this. I'm looking forward to getting it set up.
