Purchased a home several months ago with a 4k gallon koi pond. Five 24" koi, one little guy about 7" long.

Water has been tested and deemed balanced, I keep the filtering systems properly maintained and the water is crystal clear.

One 24" koi began getting "fat" a couple months ago, and now is very heavy. Fatter on the left side, which would suggest she is carrying eggs.

Otherwise the koi seems healthy. Vigorous movement, eats regulalry.

None of the other fish seem interested in spawning.

It is now October, and water temp is 65F.

Given the age of the koi, do we just let her re-absorb the eggs? I don't know what next steps should be, nothing seems to be changing day to day with her.

This doesn't look like eggs to me. More likely a tumor.
WG; when I scan the pics, I see something tumor-like near the head/shoulder, but the body sure does look egg bound to me. Care to extrapolate your diagnosis? Not that I'm an expert or anything...

No expert either. Egg bound fish to me look more round than this fish. This one is more oval looking, swelling all along the body, not just in the belly area.

But then, I'm definitely not always right!

I figure the waterwheel was at least close! (have NO idea what a 'low' miller is, but the last part!!!!)

naw, was looking for ammuntion against GB if he ever employs his anti-brokensword anigif! a motorcycle that falls apart would be MUCH better as he'd have no wheels, right? Hard to catch me without that! Heh.

You just need to do a few tweaks and he can't catch you!

Here’s a question: the bound egg theory caused me to make a wild assumption that this fish is a female.

What’s the best method to determine sex?

If this is a male fish, then this is obviously a tumor?

And if it’s a tumor, then there is nothing left to do?

it's difficult to tell sex among goldies and koi; koi females will be shaped a bit deeper in the belly and males are slimmer. But it takes 5 years, give or take, to figure this out and the easier is to watch behavior. If goldfish, I got nothin; again, behavior. Males chase females, so...

Male koi are leaner looking, not as round as females. Their pectoral find tend to have more color than a female's and have a more pointed shape to them. A female has a more rounded fin shape.

The female vent is usually dark pink and round and it protrudes slightly. Male vents are usually indented somewhat. Females have outies, males have innies.
