    Hi There!

    New here but I have had fish in the past although I don't remember putting this much thought into stocking but wanted to do it right this time even though I don't recall having problems before. I have been doing some research and have come up with a few different stocking options and wanted to get some opinions before moving forward.

    Details about my tank:
    No Plants
    Auto heater at 78

    I have definitely done a little switching out of fish based on lists I have seen (which is why I am asking for opinions)

    Stocking options:

    #1 -------

    ?# x tetras (of some sort)
    5 x Black Skirt Tetras
    2 x Dwarf Gouramis
    5 x Pana Cory


    6 x zebra danios
    6 x lemon tetras
    3 x platys
    3 x pana corys
    1 x 1 pygmy sucker catfish


    6 x cardinal tetras
    2 x Black Mollies
    5 x black skirt tetras
    ?# x sword tails
    ?# x Kuhli Loach


    2 x Dwarf Gouramis
    5 x Dwarf Neon rainbow fish
    5 x rummynose Tetra
    4 x kuhli Loach


    another combo of cool colorful fish :)??

    Sorry to say but none of these combinations will work as... the tetras, loaches and cories are schooling fish and need to be in a group of 6+. In a 20g, the number of gouramis can only be 1, as two will be aggressive and fight with each other, being that they are territorial. In a 20g, you can only do 2 schools of fish and a centerpiece fish. Your best bet would be #1 without the other school of tetras, +1 cory and -1 gourami. :)

    That site seems very inaccurate. For instance, a red tailed shark gets way too big and aggressive for a 20 gallon.

    Welcome to fishlore!
    Agreed with Dom90 on all points.... that site is very inaccurate.

    I will "third" everything that Dom said. I have been to that site as well. And it is very inaccurate.

    Ok, thanks... do you all have any specific recommendations for a community of fish? the tank is set to 78 deg... I just want some pretty fish that are not too hard to take care of while I am learning before I see if I want to get something bigger down the line...

    What Dom suggested would work. A Dwarf Gourami as the centerpiece, a school of tetras, and a school of cories.

    EDIT: I would avoid the fin nipping tetra species with the gourami.

    You could do 6 harlequin rasboras - very pretty, peaceful, and easy to care for. Dwarf gourami, honey gourami, or thick-lipped gourami for a centerpiece, and 6 cory catfish for the lower level of your tank.
