Just wondering if anyone has ever had all their larvae hatch and then all die before the morning (~11hrs)?  I have a pair of ocellaris who I had great sucess with initially, but this last batch died so abruptly.  I could explain more if it would help.  Was just wondering if anyone had this issue ever, and knew what the problem was?

As you know, mine did the same thing.... My issue I believe is parent nutrition as I slacked on my several feedings a day for a bit. Knowing how much you feed, I dont think thats your issue. Good luck, if you find anything that seems to be the problem, let me know as I am always looking for ways to do this better!

I was really really excited with this last batch, Seemed like I had 300+ larve and then left with only 5 or 6....

Just an update.
I had another hatch from the same clowns a couple nights ago. I cleaned the remote hatching tank really well, and added a little carbon to the system. Also did a 45 min dip in formalin/Malachite Green. Almost all the fry are alive at day 2, super excited!
Not sure exactly what did it, if anything. But I'm going to do all those things form now on each hatch.

Scott - It's really tough to explain why the sudden die-off occurred last time, but many breeders have reported that after they cleaned (read: sterilized) the hatching tank and filtered the water through even a small amount of carbon just like you did, the problems ceased. There are so many compounds and tiny pests that can cause problems for larvae and those who practice fastidious cleanliness bordering on the obsessive seem to be the most successful in getting the babies through. Good luck with this batch!!!
