Egg Parasites? Fuzzy Eggs With Moving Specks

[guppler]

I decided to go a head and take eggs out of the comunity again this time, but the 10 g was full of frog and loaches, so I put cory eggs ina series of plastic critter keepers with 1 of the sponge filters and 1 of the bubble wands.
I usually get some eggs that never hatched, and some of them look different. about a day before they started hatching this time, I noticed at least 1 egg looked very cloudy, white, opaque, kinda fuzzy, but it was right next to some that looked good, and it was almost hatch time, so i didn't want to mess with anything.
Yesterday most of them hatched, but a few were still not hatched today, and they looked like they might have yolks or fish in them , so I tried to get a closer look with a magnifying glass. The 1 egg that was definitely fuzzy was surounded by tiny whitish specks that seemed to be swimming, but other nearby eggs looked like they had hatched. A couple of inches away another clump of eggs had some of the moving fuzz as well as some eggs that looked healthy except that they were not hatching and I didn't see anything moving inside. One even looked like a pretty well develpoped fry with eyes, but the last time I watched with the magnifying glass on hatch day a lot, most of the babies were wiggling around inside the eggs.
Does anybody know of a parasite that kills babies in the eggs, and might be what I have?
I do have some pretty healthy looking fry, and if somehting has killed some in the eggs, I wonder if it will also kill them after they hatch.
What are the chances that this is not going to hurt them, or that the fry can actually eat the microorganisms?

When my cory eggs were on the glass I too noticed little things moving about my eggs. Mine looked like super little tiny worms they appeared to be only interested in the eggs that were dead or already hatched, but I placed some fast moving water from my filter out let over the eggs just in case they were going after the living eggs, to keep them away from the eggs. My guess is that they are some kind of common fish parasite that are introduced when you add fish, I have not found them to be harmful to my hatched fry and they are probably making meals out of them.

The one egg that is white and fuzzy most likely has fungus on it and you need to remove it. If you dont, the fry and any remaining eggs may be harmed.

I agree the fuzzy eggs have been attacked by fungus and needs removing. The tiny white worms are Planaria Flat worms which are non-parasitic,they only eat dead flesh. So they're probably after the fuzzy eggs. Go to tyhis web site for more info on them http/en.wikipedia.org/wiki/Planaria. Some Aquarists don't like them, but I had them with one of my Cory batch of fry and after a couple of weeks the fry was feeding on them.

update
at last count it looks like I have over 40 healthy growing fry. So whatever was swarming around the eggs was probably helpful or neutral.
I haven't really tried to look for the tiny wormies lately, but I imagine the fry hqve found some tastey wiggly treats.
I've seen similar wormies in my tanks before. In fact this same plastic tank had yellow guppy fry a few months ago ( it has sinse been cleaned and dried and lived in by bettas and dried and cleaned again), and then it had white wormies that had sticky tails at one end and wiggly mouths at the other. I looked those up and found a reasonable ID, but forget what it was. This time they were so tiny it was hard to tell if they were roundish or linear or swimming or crawling, but they seemed fast for crawlrs. I like the idea of planarians or flatworms that don't eat live fishies and eggs, even though i'm not sure that's exactly what these were. Planaria are pretty cool. i've seen some pretty big wild ones in green gooey ponds and found some related garden varieties over 6 inches long (_Bipalium Kewensis_) under rose bushes after rain and in potted plants. Neat critters, but I wouldn't want the big ones in with my fish.
Anyway It looks like I didn't have a dangerous parasite this time, and i won't mind seeing them again.

They probably have "egg fungus"

Heres a article for more info

thanks for the link. It looks like good info. I'm sure i did have fungus. I might even have it in the new eggs. That's right, they spawned again, except this time I'm not sure BC is the mom. I found a couple of small egg clusters and Pinki was definitely looking frisky, but one of the larger fry was looking a little excited too, and I didn't see her of BC holding eggs, and didn't find more deposits. Now all but about 2 of the ones on the glass look whitish and opaque. The clearer ones might even be empty, because the minows and tetras pick at them a little and snails crawl on them. I was going to rescue them, partly to see if some of the fry would turn out to be albinos, but I think there aren't enough healthy ones to bother.
The fry from the batch before are looking good so far. I was considering moving them to tank one with some mostly female guppies because they are almost as big as new born guppy fry. i might wait, but coincidentally, it looks like somebody dropped some new guppies too. It could be an oportunity to compare them directly.

Hi guppler

I'm glad to hear that your cory fry are doing well. Please don't be in too big of a hurry to move them in with guppy or even guppy fry. Even month old cory fry are still like little babies. They are defenseless and if the guppies spot them they are apt to be done for.

I've been having trouble with fungus attacking a lot of my eggs too. They look like what you describe. One recent batch was a total loss except for about 10 fry. Sometimes adding methylene blue might help, but I can't even find any at any of the lfs near me. It's such a disappointment when that happens.

Don't wory inchworm. The cory fry are still in their own private tank. i even cleaned it up pretty good today, and I think there are around 50 of them. Of course some snails snuck in with some of the stuff i moved in with the eggs, so I picked out some snail egg jelly and offered it to the loaches, and just tossed some out with the dirty water. I think some of the cories are about as big as the newborn guppies, but I don't have to move them.
i might have to move some of the older fry though if I want to continue to know which one is BC. I found a tiny cory in with my guppies that definitely has something wrong. It's way smaller than the others and has silvery eyes as if it has cateracts or something. I think Winki the 1 eyed fish was bigger last time I saw him, but it could be Michael or Phinagan. I'm calling it Penguin now becaeuse it is very white on the belly and almost black on top. i think Penguin has to be about 4 months old and only about 1/2" long, and kinda skinny. Then there's Shorty. If you imagine a normal cory as a bag with a loose drawstring around the tail, it's like shorty's string is pulled too tight and crummpled a little. He's plenty fat until you get to where the peduncle should be. Then there's just nothing but a little tail. He'll get to stay with Flipper and Kneela and Penguin, but most of the rest are ready to go. My art teacher said he'd take 2 or 3, but he doesn't like the albino ones, and wanted to be sure they wouldn't have creepy red eyes.
It sounds like I got lucky this time to get so many healthy fry. I didn't even treat the fungus or do anything special. maybe the wormies ate the bad fungus. I couldn't even find baby food around the house when they first hatched. Had to get more, but they seem to like daphnia, which I had around.

Hi guppler

Keep up the good work!
