Fish Tank Showdown: 20 Gallon High vs 20 Long!

Hello Fellow Fish Keepers! A 20 gallon fish tank is a great size for someone who wants to keep a nice variety of fish, but doesn't have a lot of space or doesn't want to invest a lot of money. There are two main sizes of 20 gallon tanks - the 20 gallon high and the 20 gallon long. In this video we look at both, and break down the advantages and disadvantages of each. If you have a preference for one over the other please feel free to share that in the comments section below. Thanks for watching!

Hi Everyone - at one point in the video I say a 20L is 3ft, I meant 30in (which is what I say in the rest of the video). Thanks for watching!

I loved the video of the comparison. I love my 20 long. It gives the impression of a large tank and like you said the real estate is bigger. Thanks so much for sharing.

I have Finnex Stingrays on most of my 20L and they work fine for low light plants.

I'm a big fan of the 20-long, particularly as a first aquarium.

I’m probably the only one that would prefer a 20H , just like the looks of tall plants

I don't think you're the only one. Haha. I have five myself so I see the value in both.

I know this is nitpicking but a 20 long tends to be better for oxygenation because of the surface area too. This allows me to grow out a little longer before moving the fish into another tank.

That is a very good point!

I picked up one of each during the Petco $1/gal sale. The 20L is in use with my Platy fry, the 20H is still un-used. Guess that says which I prefer. I might try and find a 15. Same footprint as the 20H but not as tall.

I'm sure you will find good use for the 20H as well! : -)

I'd choose the 20 long as well for the same reason. I'm a cichlid keeper first and I keep plants for ornaments and functionality.

Note, a 20 gallon long is 2.5 feet, not 3 feet. 3 feet tanks are usually either 30 gallon long, 38 gallon, or 40 gallon breeders.

Yes, just noticed at one point in the video I said 3ft instead of 30in. Nice catch!
