20 gal high, or 20 gal long

  1. Daniel W Member Member

    Well, sometime in the future I want to get a 20 gallon. I'm just not sure if I want to get a 20 gallon long or a 20 gallon high. For this tank, I hope for 2 honey gouramis, 6 cories (still haven't decided what breed yet. Advice is gladly welcomed.:)), and around 7 bloodfin tetras. I want which would be a more appropriate tank setup, a 20 gallon long, or a 20 gallon high.

    20 Gallon long - no question! Larger footprint means more horizontal swimming room for your fish. Your stocking plan sounds good, too!

    A 20 gal tank usually comes in landscape( laying on the side ) or portrait ( standing tall) versions
    and for the fish you want you should get a 20 gal that is a landscape version so that you can have room for more substrate plants and room for fish to roam around

    Thanks for the advice! But the only reason I ask is because I read in another thread that a 20 gallon high tank is better for a community set up. I think it was because there's more space in the different levels, making the fish more comfortable. Not sure if I should take that in account.

    20 gallon long has a bigger footprint for the fish and more surface area for oxygen exchange. A 20 high may have more vertical space for levels, but these levels have more limited amounts of swimming room for the fish.

    Okay, thanks for the advice. Just to clarify, the reason a 20 gallon long would be better would be because of swimming space and oxygen exchange?

    Long gives more horizontal space. IMO in a community tank, all fish should be peaceful thus it shouldnt matter if they merge into other areas to explore.

    Bigger footprint is best.

    20g Long.

    Ps in all stores I see they are L or T (long or tall) is vert/horiz in UK or not America???

    A 20 gallon tall doesn't mean vertical, it just means a short rectangle. Looks like your normal 10 gallon.

    Yeah tall is vertical, long is horizontal. Did I say something else? Sorry!
     
  10. Daniel W Member Member

    Oh! I thought by vertical you meant one of those really tall tanks! Sorry!

    2.5, 5, and 10 are all the same 'ratios'

    20 have tall/long.
    -tall is more like a 10g that is taller,
    -long is same height of a 10g, but wider

    Thus a long, is shorter, and more side to side. Not as much height. This is generally better. IMO Long>Tall always.

    Tall is taller like a 29/30/33, just not as wide.
