These fry where about a little over a week old. All doing great, eating swimming great. Christmas eve night i noticed some swimming on the bottom like they were eating, but they were straight up and down. And when they would try and turn they would bend completely over and not really go anywhere. They were still eating, so i didn't know what to think. Christmas day those i had noticed were dead or close to dying on the bottom so i removed them from the tank. Later that afternoon about 10 more were doing the same thing. So i changed their filter, and did a 20% water change (its a 1 gallon, i change 10% with fresh water, and 10% with cycled water from the parents tank since the fry tank was not yet cycled) I found those 10 dead that night, and most if not all the rest acting the same way. I couldn't go anywhere with everything closed on Christmas, and turned their light off and hoped they would be ok. Wednesday morning. All dead. I don't know what happened. Actually i have raised molly fry before. But always in the net breeders so the water conditions where very constant. Did i do domething horribly wrong? Was there something genetically wrong with them? Was this something that i could have treated if i had caught it earlier Christmas eve? The parents are fine and also got a water change with the same fresh water and new filter. Help?!?

How many fry did you have in the 1-gal tank? With that small of a water volume, the water quality can go downhill fast. I change 50% daily on my 1-gal cory fry tank, making sure to use Prime on the new water before it goes in the tank.
I wouldn't use the parent's tank water when you do a PWC, either. Use all fresh, dechlorinated water. Using water from your other tank will just be adding more 'trates, and won't help the cycle on the fry tank much. Putting some filter media from the big tank into the fry tank's filter will help more. (It does have a filter and heater, right?
)
What were the parameters on the fry tank?

They have a Heater and Filter. But it's one of those small in tank filters. I guess next time i know better. Actually next time, I now have an extra 10 gallon tank that had female bettas but i gave them to a friend who really wanted them. So i am thinking of putting the fry in there instead. The fry where only in the 1 gallon because they were born the day after i got the female, and i had no where else to put them. And i wanted to try and save as many as i could. Do you think they would be ok in such a big tank at first?
Also wanted to add. The fry tank had no gravel in it, just one small plant (had a little bit of gravel in the base to keep it sunk)
Also wanted to ask. In the past I fed Hikari first bites and they seemed to due well on it. This time the store was always out. So they were being fed finely crushed adult flake food. Are either of these foods ok? Any suggestions on feeding them in the future?
Thanks,

how big is the tank where the parents are?? if you can next time get a 3in1 breeder tank and keep the fry there for 2-3 weeks atleast until they get bigger and are able to eat flakes, brine shrimp without a problem. Then you can start moving them to either their own tank or even their parents tank (unless you have other fish in there other than mollies who can eat them)
Feeding finely crushed flake food is what i did and they ate it without a problem, no point to spend extra money on fry food.

a 1 gallon tank is a little tight for fry, even if there are only a few of them.
the water in the tank holds very small ammounts of bacteria. if you squeeze the media from one of your established filters over the 1 gallon (or soon the 10 gallon's) filter(s), then it will help cycle the tank better.
