The Mr. Aqua 3 Gallon Bowfront tank is an awesome little nano tank that can easily be placed on your desk, kitchen counter, or really anywhere with its small size. The small pico tanks are best for smaller species of fish, corals and invertebrates. Many people will use these tanks for a single species of coral, or invertebrate that may be a bit harder to keep in a larger community system. The Mini bow front tanks can be drilled on the backs as they are not tempered if you wish to add a sump or closed loop water flow system.


We like to use smaller pieces of Fiji and Reef Saver rock in the 3 gallon Mr. Aqua tanks. Those two rocks we usually have smaller sizes on hand and can be used to make aquascapes that fit the tank very well.



  • Glass thickness: 5mm
  • Dimensions: 11.8" x 7.0" x 8.3" (LxWxH)
  • Total Volume: 2.5 US Gallons


Mr. Aqua aquariums has been producing some of the finest nano and pico tanks on the market. With their low cost and simple "glass box" design, it is much easier to customize to your needs than all in one aquariums. All Mr. Aqua tanks have a rimless design with super clean silicone sealing the tank together for years of beauty.

Product Questions

I understand this tank doesn't come with a cover, but I'd like to buy one that fits. What product would work best considering this tank has a curved front? Thank you.

Hey there! You would have to DIY a cover for this tank, or have someone make one for you. I would seek out an acrylic shop or glass shop who can cut the top to fit perfectly! :-)

Yes, it says this is 9.8" x 9.8" x 11.8", but in the image the depth looks different from the height. Can you clarify on the dimensions?

Great question! Bowfront is a little hard to measure however the site can use the correction the actual LxWxH is 11.8 "x 7.0" x 8.3"

Can the tank be drilled on the bottom? The description only says on the back...

Great question!

Answer by: Connor on Mar 2, 2016, 5:13 PM
So is the volume of this tank 3 gallons or 2.5 gallons?
Question by: Christina on Jan 21, 2016, 9:18 PM
Great question!
Often manufacturers will round up on the product description. the tank while sold as the 3 gallon will only hold around 2.5 gallons of total water. Feel free to let us know if you have any further questions!
