Have you checked the water conditions latley? That might be killing the fry and the other fish in the tank could also be harming them

i've been adding new water once a day and taking some out.i do about a 25% change of the water.i may now have a good batch.i have a bunch of them swimming around the bottom of a bucket.this time i hooked up a heater in a bucket of fresh treated water and a airstone.so far so good.now i just have to get my cory to slow down on the spawning.once a week isnt good.thanks for your help.
