Hi Brian;

This picture is of the L-398 fry in a breeder box taken from underneath. I had 2 - 3 eggs fungus, but most of them have developed. I added a tiny piece of driftwood yesterday and they all immediately congregated beneath it. It's not a good picture but even my iPhone is out of date. :o

As you advised, they need to feed before the egg sac is used up. The first one started to move around yesterday, so I assume it's feeding time. My microworm culture is not working, so Plan B is Repashy Morning Wood. You can see smears of it at the bottom of the photo, toward the left. Plan C is Golden Pearls, a 5 - 50 um micro fine grind.

Willie

I suggest a lot of aeration and a heavy dose of meth blue. A heavy dose is when you cannot see through tank. Unhatched eggs and dying wrigglers will not fungus. Find out native water temp when these fish breed and replicate that as well.
I have heard wrigglers will not eat. Once they are all wiggling, I would add some rotifer or similar sized golden pearls. Unconsumed rotifer will not fungus due to meth blue.
CONGRATULATIONS!

I agree hand raising them would be much easier. Never done leopoldi, but I usually put the slate/cone of angelfish eggs into straight tap water. I'll add dechlor after 48 hours (they usually hatch in 60 hours). That way, the chlorine suppress any fungus growth. That approach usually works better for me than adding methylene blue or other fungicides in the hobby.

Good luck with those, Willie

Granted I've never added that much methylene blue. You must have lots of blue tanks, Bob. :)

Blue stained tanks are a calming color??

Thanks! When the eggs hatched I turned the aeration down (although not off) to avoid flinging the wrigglers around too much -- it sounds like I should aim for more motion. I'll add some more meth blue too; there's a fair bit in there already (along with some acriflavine).

I like to see wiggler pile turning over a bit not just wiggling. Unless natural breeding occurs in pools, I like to replicate a little current.
Exceptional spawn. I understand this species is difficult to spawn. Nice work!

A week later and shot from the same angle. The L-398's have definitely grown a lot although the yolk sac is still visible on some. Repashy Morning Wood is the bomb!

Thanks to Bob's advice most of the Leopolid wrigglers survived and now they're eating. Am I likely to need to do a lot of culling or is that more of an issue with domestic/inbred angels? I'm trying to get some sense of how much tank space I'll need next month :)

Even if you culled 90%, you're still going to need a lot of tank space. Get ready for water changes! :o
