Week old baby green terrors

[Asuma loves fishes]

I have less than a week old green terrors fry. I removed them from my tank and put them in a 10 gallon tank with a heater and air bubbler. Today I saw a lot died so I added a filter hoping they won't get caught. What should I do. I don't want the rest to die. Help please
