GoldiesAgain 14 Posted May 10, 2019 Hello. This fish has been living in my koi pond for 2+ years. This spring, I noticed this lump, marked by arrow. From the top, its really obvious. Other side is normal. 0 Quote Share this post Link to post Share on other sites
Arctic Mama 3,625 Posted May 10, 2019 Likely it’s nothing, but if you can put your goldfish in a bowl and take a good macro/closeup under bright light of the affected area, from both top and side, it would help immensely. Also please fill out this form with details from the pond he came from, it will help us troubleshoot if this could be environmental.

koko 14,335 Posted May 14, 2019 Do you know if this fish is a male or female? I have seen this before. It can either be egg bound or there is a cyst growing inside the fish. 0 Quote Share this post Link to post Share on other sites
GoldiesAgain 14 Posted May 15, 2019 I believe it to be female. 0 Quote Share this post Link to post Share on other sites
koko 14,335 Posted May 15, 2019 @Arctic Mama I think this might be a cyst in side. What do you think? 0 Quote Share this post Link to post Share on other sites
Arctic Mama 3,625 Posted May 15, 2019 Hmm.... does this fish defecate normally? What do the poos look like? If you fast this fish does the swelling change at all after three or four days of no food? 0 Quote Share this post Link to post Share on other sites
GoldiesAgain 14 Posted May 17, 2019 Seems to poop normally, but only saw that once. I haven't seen any fish poop in many years. Brown, solid. No change to the swelling. 0 Quote Share this post Link to post Share on other sites
Arctic Mama 3,625 Posted May 17, 2019 It could a internal cyst, tumor, or egg-binding, none of which are really easy to treat. Sometimes adding lecithin to gel food can help with egg binding but it’s not a very well proven treatment, and unless the fish is showing other symptoms I wouldn’t want to use antibiotics to treat something that likely isn’t bacterial. 0 Quote Share this post Link to post Share on other sites

Lets just keep a close eye on it. Keep the water conditions nice and clean too 0 Quote Share this post Link to post Share on other sites
Arctic Mama 3,625 Posted May 22, 2019 She looks healthy except for the lump, was there a specific concern you had with the image? I can’t see both sides well because of fins but she is a pretty fish with good color (nothing that immediately screams infection like red patches or blanched body color) and no dropsy, so that’s all good news 0 Quote Share this post Link to post Share on other sites
