Help!!fries keep dying.

[Fabian]

What is wrong with my one month old fry??They are dying one by one.
I feed them,do some water change,no heater because i live in a warm climate,small sponge filter,no light(can't afford one).
The spawn off a few hundreds became 8.What did i do wrong??

I also saw some fry breathing very hard and darting around then lay at the bottom.Does microworm have any harm to the fry,because i saw some microworm sticking on their bellies wriggling.

Any help would be much appreciated.

Micro worms don't stick to fish... that sounds like parasites.

Have you covered the top of the tank to keep the humidity high?
MrV is right, microworms don't stick to the fish at least never in my experience.

Your tank must have been infected by some sort of parasite - by the sound of it, more than one. Move your fry to a different tank with new water. Make sure the water temp in both tanks are as close as possible. Then thoroughly clean your tank. If you don't want to use chemicals, leave it dry for a few days before reusing it.

I've changed the water everyday and change their tanks every two weeks
and i am sure those are not parasites because my fry keep laying on the bottom.
