    Hi all,

    My question is if I put 2 black skirt tetras,2 white skirts. and 4 glo fish in in the 20 gal tank they should school together shouldn't they? They are all tetras and basically the same size. Am I right? Thanks.

    No, but partially.
    The GloFish and white skirts will school together, they are the same, just colored. Black Skirts are colder water fish, and they probably wouldn’t school with the others.

    Maybe the black skirts wont school with the others so should I add 1or 2 more black skirts . Also if I do that should I cut down to 2 white skirts and 2 glo. because I think a 20 gal tankcan only take 8 fish of this size. Right?

    IIRC, all color variations of the Skirt/Widow tetras were the same spp (Gymnocorymbus ternetzi).
    None the less, mine school all the time in my 30, I've got 2x Black, 2x White and 3x Glo.

    I would only do eight skirts if you plan on other fish.

    Is this a 20 lon or a 20 high?
  7. cody11Valued MemberMember

    20 long.

    Thanks for your answer. When you started to stalk your tank how many did you put in at a time and how long did you wait to add more?

    They were the first, I picked up the Glo and Whites first and about 3 weeks later I decided to add the two Blacks more on a whim than anything. They were the last two in the tank which also has 3 Platies and 4 Cherry Barbs.

    So glad you wrote back. So in a 20 gal I should be able to put 2 blacks 2whites and 4 glos. That makes 8 fish is that ok?

    20L right? Depending on filtration and wc scheduling, tentatively I don't see where there would be any issues..
  11. cody11Valued MemberMember

    Yes 20 long. Has filter, bubbler and I do water changes every week, If I put 4 in first and then in a week add the other 4 sound ok?

    Is the tank cycled?

    The tank itself is fine, all that remains is adequate filtration and tank maintenance. As long as you keep up with that you shouldn't have problems (don't quote me on this, as problems have a nasty habit of showing up when everything is fine.)

    Funny you should bring that up. I just got over loosing a tank full of fish from ick. They all died. I have had fish for years and never had that problem. I think I put too many in at once and they couldn't handle it. This is why I am going to take time adding the fish.

    Hi all.

    Just realized my 20 gal tank is high. So I wanted to put black skirt, white skirt and glos. Should I put 6 or 8 in tank? Thanks

    This has nothing to do with my previous question. Now people wont answer this. When I previously asked about stocking this I thought it was a 20 long but its not. So question is different.

    Speaking from dimensions, since I don't know how adequate the filtration is... As a species only tank I would do 8 or 9, as a multi tank I would most likely reduce to 5.
