so how do i know when a KOI fish is going to lay EGGS?

Answer 1

When she is full of eggs she will be lager and fatter than a male and will feel kind of soft around the belly. Here's a page that should answer all your Koi breeding questions.

Congratulations (mom or dad)! Since Koi are not mouthbreeders, if you leave ANY fish (including the mother) with the eggs they will eat them and by tomorrow morning there may not be one left. Normally a pregnant female is placed in a floating hatching tank floating within the main tank, and it has an angled bottom with a slit so the eggs laid fall into the bottom and are safe from the mother, but it's too late for that. A floating mini hatching tank is still the best solution but 24-hour pet shops are a bit hard to find so until you are able to get a small floating hatchery tomorrow, see if you can devise anything that floats that can contain the eggs until tomorrow. It should be made of plastic or glass, and it should have plenty of holes to allow water circulation but not hungry fish into it. A small plastic colander may do the trick but make absolutely sure that if it does have some metal parts that they are a good grade of stainless steel (would be completely non-magnetic). Do not use an all-stainless colander since I am not sure what effect being in direct contact with the metal would have on the eggs themselves (3-headed fish?...). Best of luck, and read up a bit on the care of Koi eggs and hatchlings, as I cannot provide advice on that since my "fathering" experience is limited to egglaying mouthbreeders and livebearers.
