Good work. Are the fry swimming yet? Once they start swimming you need to start feeding them live baby brine shrimp. You could try to feed them frozen baby brine shrimp, but the fry will grow slow and be somewhat stunted.
You can get the fry out as soon as they are free swimming and move them to another tank (bare bottom, sponge filter, heater). It will make feeding, water changes and monitoring their progression really simple. This will be a lot easier than trying to raise out any in a decorated tank.
