    Hello! I currently have a 10 gallon with a school of cardinal tetras and some cories. I have been looking into an upgrade to a 20 gallon planted long or high with the following stocking:

    2 Dwarf Gouramis (Male/Female)
    8-10 cardinal tetras
    4 emerald green cories
    Haven’t decided on plants yet

    With the following equipment:

    Marineland Penguin 200 filter
    Aqueon 150 watt heater
    Beamswork DA 6500K LED lights

    Questions, comments and critiques would be greatly appreciated :)

    Do not do 8 dwarf gouramis in a 20 gallon! You could do a male/female pair but definitely not 8 of them.

    A 20 long is better than a 20 high.

    Bump up your cory numbers to 6 or 8 and your stocking would be just fine. So:

    2 dwarf gourami (m/f)
    8-10 cardinal tetra
    6-8 green corydora

    Should work just fine.

    I originally said 2 Dwarf Gouramis, if I’m not mistaken. The variety of cories is a bit larger than say, a panda or peppered Cory. Should I take that into consideration?

    I must have been mistaken, I could have sworn it said 8!

    Green cories are a larger variety but 6-8 should still be fine in a 20 long.

    Looks great, just keep in mind the cories will do best in a group of 6 minimum, you could get away with 4 or 5 but 6 is optimal with your current settup.

    Are greens that much bigger than peppers?

    My female peppers are all of 3”.

    I've seen green and bronze cory cats reach that size before.
