I have a nice koi pair that has spawned at least 5 times, but the fert rate sucks. It is maybe 30%.

Is their any reason why the fert. rate is so low? ( btw: I know they are a male and female because I have seen their breeding tubes).

Within 1 day, at least half of the eggs turn white. I maybe get 100-150 wigglers out of the entire spawn.

( Their are pics and videos of the pair and their spawn in the gallery). I took the pics during and immed. after the spawn so I will update the thread tomm. to show you how many eggs have turned white.

Also, another weird thing with this pair, is that the female will lay eggs over each other. Does anyone have a pair that does this?

She will go over the same row(s) 3 or 4 times adding more eggs each time.
 
From your threads you've had such great success I'm with you it's weird. As a suggestion I don't know about Angels but if I recall correctly one of the recommendations for such a problem was to temporary turn off filters assuming currents would have an affect with Discus.

Good Luck!
 
I've had some issues in the past with lazy boys not holding up their end of the bargain. What are you feeding them as far as conditioning food. I'm not certain of the exact physiological effects of proteins, fats and carbs, but it makes sense that they need something in their diets just to form the eggs and allow the generation of the sperm. I had some success switching to black worms, but if you're not already using them they can be a hassle, expensive, or both. Maybe your food's stale?

Another move was a cleansing session with Potassium Permanganate. If you haven't tried it before I'd suggest somebody elses tank before you use it on the koi. As soon as I was done everybody was up 'n at'em cleaning sticks and the resultant spawn was much improved.

Also used an egg crate divider to introduce a neighbor pair that were top performers. The hormones released by the rambunctious pair usually gets the slackers in gear. Lastly I've also had some luck with dither fish and introducing the pair back into a community tank. For dither fish I use my c. habrosus. They're a pygmy/dwarf variety that don't bother the eggs, but I have to remove them as soon as the deed is done or the angels will worry the corys to death.

Thanks. Well, this pair is kept with (2) other pairs in a divided tank. The other pairs have a 85-90% fert., rate and they parent raise. ( I believe their are pics of them and the fry in my older threads).

( all my pairs eat flake food, sinking pellets, and froozen bloodworms). I alternate foods every day and provide a 25% water change every other day.

I have been breeding angels for over 7 years, and this is the first pair that just can't seem to get it right.

I did email the seller, and found out that they are siblings, so that might have something to do with it.
