20-gallon (76 litre) tanks

Tanks this size are ideal starting points for anyone entering the hobby. In the United States 20-gallon tanks are available in “tall” and “long” varieties. The tall tanks measure roughly 24 inches in length and 17 inches in depth; the long tanks are 30 inches in length and 13 inches in depth. All else being equal, the long tank is better. Long tanks offer more swimming space and have a greater surface area to volume ratio, meaning oxygen diffuses into the tank at a faster rate. You can keep more fish, more happily, in a long tank than a tall tank.
Do tall 20-gallon tanks have any advantages? Not many. They are perhaps a bit easier to decorate with tall plants and rocks, and having a smaller footprint they take up less space on a tabletop or shelf. Greater depth does work better with certain small but tall fish, in particular domesticated angelfish. But beyond that, these tanks are far inferior to long tanks for general fishkeeping and are best avoided by less experienced hobbyists.

Species useful in 10-gallon tanks will do even better in a 20-gallon tank. In the case of things like small tetras, you can keep larger groups. If you have a nicely planted aquarium, consider keeping two dozen neons for example. Otherwise some of the additional species you can sensibly keep in a 20-gallon tank include the following:

The Mr aqua 12 gallon long aquarium is actually one of the best tanks i’ve ever had a chance to aquascape. With these unique dimensions, you have to really use your imagination with depth of field and how to turn this 2D dimensional tank into 3D. I personally went with an iwagumi style for my 12 gallon long because of the sheer length and ability to use space to create a focal point. It’s almost the doppelganger of a traditional aquascape, where you use hardscapes or aquatic plants to create a focal point.

Ok to the question at hand! The Mr Aqua 12 gallon long aquarium does come in at 35.4″ outside dimensions but even though the Current USA Satellite Plus says 36-48″, it comes in at 34.8″ long. Which means it does fit perfectly on the 12 gallon long, giving you the most bang for your buck if you are looking to light up the whole aquarium.Hi! Great article, super helpful. About 2 months ago we set-up a small 5 gal aquarium, and got 3 Rasbora harlequins, two of them died. I was thinking adding more buddies for the little guy so he’s happier, but now after reading your article, I am hesitant… I also read Rasboras need long space to swim. Would you think it best to add smaller different specie? Or a few more Of its kind since they are schooling fish? I don’t have live plants but will like to add some too, it doesn’t matter if the fish are already there right? Your advise is super appreciated, thanks!
