they should hatch by tonight. if not, they may be unfertilized or something else went wrong. use a flashlight and look for a tail, it should be quite clear but slightly visible
If it was a "poor" spawn, then there might simply not be any viable eggs. They should definitely look a little more opague in color and yes, you should see what appears to be a little tiny tail sticking out of them. If they are still bright white or, worse, if they are fungused, then you will not have fry.
