  1. Default Goldfish - horrible lump

    0 Not allowed!
    Hi everyone

    My goldfish for over 6 months has developed a large lump on its
    back, tried many treatments from the pet shop but nothing seems
    to get rid of it.

    just come back from holiday and noticed the lump now has
    chunks almost eaten out of it, looks horrible. There are 2 goldfish in the tank
    the other fish is healthy. Before i went away i did buy some more fish
    disease and on my return seen the chuncks taken out of it, not sure if its the
    disease treatment breaking it down?

    ive uploaded a video to youtube so you can see what it looks like

    Can anybody advise what i should do or whats wrong with it?

    many thanks

    looks like a tumor of some sort. The fish does not seem to mind it yet either. I would try to remove it surgicaly and isolate that fish so it can recover.

    hi thanks for the reply

    no it doesnt seem unwell, although sometimes it does
    sit at the bottom of the tank.

    Would i need to take it to my local vet to get it removed?

    It could be a cancerous growth. Looks more like a growth than a abcess. It's leave it as it is since the fish is doing OK. Since you're not a vet, you could do more harm than good.

    Read up on Lymphocystis. Seems to be rather common in goldfish.
