    Default My Goldfish don't Grow!


    0 Not allowed!
    Two fancy goldfish were part of my first purchase when I began fishkeeping. Once I started to learn the actual rules of responsible fishkeeping, I got them a 60 gallon tank and increased their number to four. The tank looked so empty but I told myself that eventually there'd be 6-12" monsters nicely filling out the space.

    The thing is... my goldfish have never really grown. I've lost a few, I'd had others for years, and not a one has gained any noticeable size. Now, I understand that goldfish are supposed to be slow growing, but I've got clown loaches in another tank, and those "slow growers" put on obvious size in the months after I got them.

    I've gotten little goldfish that stayed little, and medium goldfish that stayed medium. My tank is understocked and overfiltered for the bioload that's in it. I'm tempted to admit that these fish just aren't going to reach the size some due, and go ahead and add a few more of them. What do people think? Why aren't these guys growing? Genetics, or something I'm doing?

    Assuming there are no chemistry issues, what do you feed and how often ? I would recommend a high quality, high protein slow sinking pellet, make sure it contains some vegetable matter, and you can treat with bloodworms or brine shrimp, even mysis.

    Actually a high protein diet is bad for goldfish. It is true they are omnivores, but they require more vegetable based food or they will develop digestion problems. Of course Brhino knows this.

    Brhino, I'm not sure why your goldfish aren't growing but I'm not sure adding more is wise simply because there is no guarantee the new additions won't grow to their full potential. Then again, if the new additions do outgrow the old fish it is a great excuse for another tank.
    When I go fishing I just place a sharp rock in the water and sit there waiting for all the dead fish to float to the top... Kingfisher
    Brutal honesty will be shown on this screen.
    I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
    Tolerance is a great thing to have, so is the ability to shut up.

    I can explain it to you, but I can't understand it for you.

    +1 to the above

    IMO fish can sometimes be like people. Some people will grow to 4'0" while others will grow to over 6'. Perhaps your fish were just never meant to play in the NBA ?

    I know you keep very good water quality and feed good quality foods. The only thing that comes to mind for me is that perhaps this is related to genetics or the care they received before you got them.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Maybe a detailed tap water analysis might show something that would explain it? Just throwing out ideas...Maybe some kind of slow leaching contamination in the substrate or decorations, was it used when you set it up?
    Are the fish from different stores/stock?

    crazy...they grow malformed in tanks that are too small for them, but don't grow in a properly sized tank...

    Thanks for all the responses. To answer questions -

    Food is standard NLS stuff. Short of an ideal diet I'm sure but ought to be plenty good enough.
    Anything in water / decor / etc that stunts growth would have to be something that only effects goldfish, since this is not an issue that any of my other species have experienced.
    The goldfish have come from two different stores. Some from my (non-chain) LFS and some from Petsmart.

    Could it be that prior to your getting them, they were kept in such cramped quarters that they were already stunted before you purchased them? Do stunted fish ever resume growing once they're housed in properly sized tanks? Or is the stunting permanent? To me, that would seem the most likely cause, since you take proper care of them once you acquire them.

    The answer to your problem seems elementary to me, that the tank is too small. I know it doesn't look it to your eyes, but indeed, goldfish need a heck of a lot of room.

    First you have fancy goldfish, which won't grow to foot long monsters overnight, but can grow to outrageous sizes. Generally speaking you'd need at least 20-30 gallons PER FISH. I don't have the link off hand to the goldfish growth chart, but its on this forum somewhere, so you can check the average growth of your fish according to their breed.

    If the fish were severely stunted in a small tank for a period of time, they may delay in growing, or have lifelong growth problems. If your fish are not growing a half to a full inch a month, something may be wrong with the space involved.
    2 10 gallon tanks, 1 20 gallon tank, 1 Fluval Edge, 1 29 gallon tank, and one backyard pond.

    I've thought about that, but given that I've used multiple vendors and that the ones I've gotten are from medium to small sized, it doesn't seem likely.

    My good camera is on the fritz these days. I can try to take some with the camera on my smartphone, maybe.

    That would certainly be an unconventional opinion. I'm not saying you're wrong because I don't claim to know enough to say so, but your opinion would contradict most of what I've seen, including two stickies in this particular forum. Logically, you would think that unless we're talking about a tank that is SEVERELY undersized (like the hated goldfish bowl), even if a tank were too small for the full size of the fish, it would be acceptable while the fish were only a fraction of that size. If that weren't the case, there'd be no such thing as a growout tank for fish fry or juvies.
