Dead Goldfish

    My dad has had a big pond in the backyard for 10 years now. It's freshwater and only has goldfish in it (15 or so at the moment so it's understocked).

    The filter has always been on, done water testing etc. but today when I went to feed them I noticed one had passed away. Some of the goldfish have been around for the 10 years however over the years they have bred so some are younger.

    I was just wondering if anyone knew what this goldfish died from so I can prevent any more deaths, unless it was natural causes.

    There's no blackness from ammonia poisoning however the tank is completely cycled and mature so water levels are safe! It doesn't look like columnaris (I think that's how you spell it) or dropsy either. I will attach an image and hopefully someone will be able to identify whether it was natural or from illness. We usually don't have any issues with fish passing away unless the pond happened to overflow or a bird came so it's really strange!


    Thank you

    Hi there,
    I don't see anything wrong with your goldfish, at least not any external symptoms.

    @CindiL might be able to help you out.
    Best of Luck!

    Yeah I didn't notice anything either. It could have just been one of the older ones

    Thank you for your reply

    Nothing's wrong with the outside of him. Probably age. Sorry for the loss, though.

  5. bettaa9Valued MemberMember

    Yes I was thinking that. Do you know how long they roughly live?
    I have read 10 years and that makes sense since the older ones have been around that long

    Haven't had a goldfish in a while, but 10 years doesn't sound outrageous. My friend's was 16 when it passed.

    Comet Goldfish have a natural lifespan of 5-15 years. How old was your comet?

    I asked my dad and turns out he's had the pond for 12 or 13 years. If it were one of the originals it would be about that age, otherwise they bred roughly 10 years ago.

    Hi, its hard to say from the picture but I would assume its old age unless others start dying too. Then in that case I would suspect parasites or bacteria.

    Ok thank you I'll keep an eye out. Hopefully it was just old age as that sounds more pleasant than passing away from illness

    A very experienced member in my goldfish forum saw this post and said it was dropsy. The area between the gills and the middle of the goldfish shows raised scales. I'm sorry, but this fish passes away from dropsy :(. It was also mentioned that the eye looks unusually large compared to the body, possibly caused by pop-eye which is very often seem with dropsy. One my fish actually has dropsy and pop eye now. Dropsy is usually caused by bad water quality, so please make sure to always test your water and keep up with your water changes, and make sure you are not overstocked.

    Though dropsy can be caused by bad water quality which can be toxic to the kidneys and other organs leading to dropsy symptoms it can also be caused by a bacterial infection. I agree that water quality is ultimately very important. If the fish was 10 years old, it could also be a natural byproduct of old age (the kidneys stop functioning).

    I agree with the others in that I don't see anything outwardly wrong with it. How large was this fish as it looks like a juvenile to me.

    I agree, with @slayer5590, this fish looks quite small to die of old age & if it was in a large pond I don't see how it could have been stunted.
