Fantail with lump on rear right

Recommended Posts

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.

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.

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.

I believe it to be female.

@Arctic Mama I think this might be a cyst in side. What do you think?

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?

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.

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.

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 :)
