Sigh......white film,no water movement....Did you even think you may have had mosquito larva and NOT fry? Put a tank in your back yard with a little water and see what happends...The "fry" swimming in the white film was probably hatching mosquito's....

Yup totally agree.. Mosquito or some other insect larva...I just cleaned some out of a tank in my back yard... I have also seen this happen on inside tanks where the maintenance was questionable.
