Nematode in clownfish egg

I posted this in my breeding journal, but figured I'd post it here too. Any one have any ideas as to if this is a problem? Could this be the cause of my low survival rate in the first couple days?

OK, so I watched that video, are you talking about the worm-like thing at the end on the exterior of the egg where it would have connected to the substrate?

Yes. It was initially moving around a lot, but by time I made the video had slowed to the point where it was barely moving. While it was moving, it covered a lot of the area around the bottom of the egg, not just where it attaches to the substrate. I'll admit that I don't know much about the microscopic world, so I'm not entirely sure if the nematode was in the actual egg, or just beside/on/under it. I just know that many species of nematode are parasitic.
 
I was able to get a look at the whole body, but didn't get any pics (my microscope software was having issues), but I can tell you that it looked nearly identical to this

Most probably just another harmless nematode.
Nice to see both heart cavities pumping though!
