Usually when the female joins in on the cleaning, nest building, and defending its game over!...12 to 24 hours ovulation...after ovulation 12 hours to eggs. Sometimes the Ovipositor doesnt show till last minute. I just had 2nd Kelb spawn on Friday. I think,most the time, the Orino is most difficult to spawn in captivity because the Males are so agressive and beet the females so bad that they kill the mood. You do have a neighbor that gets eggs every couple weeks though. Looks like you have a great pair! Good luck Mike
