Belly swimmers

[springer]

What would be the cause of fry never becoming free swimming. I have some fry I am trying to raise artificially and they do not become free swimming just squirm on their bellies until thy seem to fade away. Any advice would be greatly appreciated

Usually the wrigglers are feeding off of their egg sac and once the egg sac are completely dissipated normally the fry will swim to the surface.
Now if the wrigglers are fade away on the bottom of the container it may be that the some of the wrigglers are underdeveloped and too weak.
If you have any pictures of the wrigglers it may help.
