hello cichlidboy on my site i have breeding logs and how to get they rare koi convict. i breed these guys for money feeders and fun! you need to look and see if there is a small tube like growth by her anal fin. also look for protective behavior.
It's not a light switch (the colors) They will fade hour by hour and then be gone till they are ready again. First 2 are right before....third is right after.....
