  1. Default 20 Gallon Aquarium Fish Help Wanted

    0 Not allowed!
    Hi, I am a junior in high school and I recently decided to get an aquarium again( I had one when I was in 7-8th grade) I am using the same tank, filter, heater, rock and decorations; I just wanted a little input on what fish to use. I kinda want a tropical/colorful tank but prefer not to have tetras or guppies because that is what I had before. I was thinking maybe two fish to 'run the tank' and maybe another school of small fish and several cories. Any input will help me, Thanks!

    You could do a smaller school of cherry barbs (I say small because they don't stay tiny) and a group of cories for the bottom - or other people might recommend other types of "non tetras" - don't forget, there are many types of tetras, each with their own coloring - I don't know what you owned before.

    I would say no to two gouramis as I assume your talking about the popular Dwarf, because they usualy end up with the dominate killing the weaker one. All the other's would grow to big for a 20 gal.

    You could try 2 honey gouramis, they are more peaceful than the Dwarf and stay small.

    They and a school of tetras like; Lemon, Bloodfin, Flame (von rio), or Rosy would work, if you want something besides neons.

    The 20's a little small to keep the larger Cory's but you could keep one of the dwarf species.

    What about one dwarf gourami, several cherry barbs and a couple corys?

    Welcome! Cory's really need to be in a school of at least 6 - a school of the dwarf Cory's would be really nice.

    An example of them would be "peppered"/"spotted" or "albinos" - they are very cute and stay small.

    you've gotten some great advice. I love all the options you've been given.
    another thought would be to go with a flashy betta of some type - crown tails come to mind - and add some neons to compliment the betta's coloring.
    Or you could have a betta and a school or cory's too.
    Harlequin rasboras would also be a good choice for a 20 gallon.
    Have fun deciding and be sure to show us some photos :o)

    AFAIK albino are bred from the bronze cory and those do not stay small.

    There's c. pygmaeus, c. hastatus and c. habrosus that are true dwarf species. Plants, sand and a group of 8 as well as some dither fish are what they need to do well. Give them soft water and keep the temp below 24c and you got a good chance they'll breed.

    Harlequin rasboras are fun to look at in my opinion or maybe a set of ram cichlids to brighten up the tank a bit.
