    Default Overstocked?


    0 Not allowed!
    Hi all, I am new to the forum and have had fish for a year now. First off i'll say that i didn't do my homework before purchasing goldfish and just assuming that i should start with them rather than smaller growing tropical fish.

    So i have a 10 gallon tank, yes i know to small! with 3 fantails in it. Two of them are about 1 inch body and 1 inch of tail and the other is about half that size. I have had the tank for a year running and all the fish have doubled in size since buying them.

    I recently found a 20 gallon tank, i would have bought one sooner but i am poor and a student so double poor lol so i will be moving my fish to this new tank. I know now that goldfish should be 10 gallons per fish and should have got a 29/30 gallon tank but couldn't find one in my price range.

    When the fantails are still fairly small though is it a big deal not to have a large tank for them? hopefully by the time they are getting ever larger and closer to full size i can afford an even larger tank. I am thinking of getting a filter suited for a 30 gallon tank so the water will be kept extra clean in the smaller tank until then. So do you guys consider this overstocked even though the fish are little guys still?

    here are some pics of them in the 10 gallon. i am moving at the end of the month (2 days) and will be setting up the new tank in the new apartment.





    thanks!!

    i don't know much about goldfish.
    the reasons to not have them in a small tank even if they are small is:
    a) they could get stunted
    b) you will have to buy a larger tank anyways, so why not now?

    and a question i have for you is, the new tank you will be putting them in, is it alreadly cycled? or will you be performing a cycle with fish?
    currently:20 gallon tank with:
    3 african dwarf frogs
    1 bristlenose pleco
    7 swordtails
    4 hengli rasbora
    1 platy

    From what I know of goldfish, your tank is massively overstocked - i believe the rule of thumb for goldfish is 20g per fish.

    They are really really messy and have high bioloads
    30g - Planted - need to do some serious rethinking
    20g - planning

    how can it be massively overstocked if they are little!? wouldn't the tank look pretty much empty if i got a 60 gallon tank for three 2 inch fish? it is frustrating because that other guy responder in his signature says he has a 20 gallon tank with 17 fish and 3 frogs in it! and i can't even have 3? i know obviously fish have different needs and whatnot but that seems a little silly.

    for the new tank i think i will put in some of the water the fish are in now and the gravel/decorations from the current tank as well. i'll let it cycle for a week probably before adding the goldfish into it or maybe just stick the little fish in there before the big guys so in case something is funny happens only one fish might get sick rather than all 3.

    do you mean my sig?
    a)i'm overstocked.
    b) my fish are small. really small.
    you hav to think not only of how big the fish get but their bioload.
    for example:
    my three african dwarf frogs produce a very small bioload so they could probably go in a 5 gallon tank.
    however my bristlenose pleco creates a huge bioload and is practically a poop monster that he needs a 20 gallon tank so he won't die of ammonia poisening.
    makes sense?
    your goldfish is kinda like my pleco
    it seems silly now, but trust me your fish will be much healthier and you will save money if you jsut buy the big tank.
    have you done that way of cycling before? i suggest you read about cylcing on here. it's under the aquarium forum under the menu...

    You are massively overstocked because it is not to do with the size of the fish currently - its to do with the amount of poop they make and the size they get to be.

    The tank won't look empty because the fish will grow.

    As DanceThenParty admitted - they are overstocked, and not all fish are equal. Goldfish make an enormous amount of waste whereas smaller fishes such as tetras barely make any. You cannot compare pure numbers - i am sorry but you are overstocked. I was in the same boat as you (3 goldfish in a 10g too) but it is the truth - you are overstocked.

    I believe it is 20 gallons for the first goldfish and 10g per each fish after.

    my first tank was a 45 gal with 4 fancy goldfish, and i started with only a 50 gal filter. one lost fish later, ALOT of cleaning, and another filter, my fish started to grow.
    what this means to you: if cycle with fancies, you might loose one or three; as was already said, they are very messy, (i have seen mine poop tetras! ), and your tank, and i believe the one you are planning on buying are too small. if you cant get a tank bigger than 30 gal take one or two fish back. if you do get a bigger tank, i would keep them in the 10 gal long enough to cycle your new one and no longer. that is my 2 pennies.

    Like others said, they will grow, and they will grow fast. Before we joined this forum and when we didn't know a thing, we had 4 fancy goldfish in an under filtered 29 gallon, similar to the size of the fish you have, but maybe a little bigger, and our water was dark green. When I look back now I'm shocked they survived, lol.

    After joining we took the advice of everyone here and upgraded them to a heavily filtered 55 gallon, and then they started to grow fast, and we soon upgraded again to a heavily filtered, moderaltey planted 75, (there current home) Its been almost a year and we haven't lost one, or even had one get sick, and thier still growing like weeds. We also added 2 more friends for them once we got the 75 since they love to school.

    A year ago the smallest was maybe 2 inches long and the biggest was 4 inches (from nose to tail). Now the smallest is 4 inches long and the biggest (a black moore) is pushing 7-8 inches. We already have plans to upgrade them to a 120 gallon because of how big they are getting

    Basically what I'm trying to say is goldfish are messy, and they grow fast. If you plan on keeping all of them I would get a large tank from the get go. That way you don't end up like us and constantly upgrade, , lol. If you plan on just having the 3 of them, I would get a 55 with a filter rated for atleast 100 gallon, but if you plan on adding to the school I would go 75 or larger. They love being in schools. Ours are constantly playing with each other. Yours will be ok in the 20 gallon for a few months, but if they grow like ours have, it will be cramped fast. Keep an eye out on craigslist, I'm always finding awesome deals on complete setups
