Koi with eggs

My koi is full of eggs how long before she lays them? We noticed on Friday and its now Monday and no sign of the eggs yet. - Sage

Koi usually lay their eggs in late spring or early summer.  Changing temperatures are usually the trigger for the spawn.  You will notice that a couple male Koi are banging into the female one to get her to expel the eggs.

If your Koi's abdomen becomes abnormally large, it may be the sign of a tumor.  Only a trained vet can diagnose and remove a tumor.
