The rainbows sound like M.australis but then they could be anything ;-)

Why are we collecting the fry into the cup? Shouldn't we be collecting the
fry from the cup to be place into the grow-out tank after they have hatched
in the hatching container (cup)that has the same water as the grow-out tank?
In other words your hatching "vessel" should contain the same water as the
rearing tank and then you don't have to do what you are doing. Or did I
translate it wrong!
>I add a little food to the cup maybe three times during this period.
You should move the fry from the hatching container (your cup) as soon as
they (the fry) hatch using your spoon ;-) into the grow-out tank - then you
don't have to feed them until they are in the rearing tank.
>I never see the fry at the surface of the water in the tank???
Try it my way and see what happens??? Also the fry may be a little lower in
the water than just sitting on top.

All sounds fine to me! (taking note of Julie's reply re power filter)

Most rainbow fry can survive on the above!

I think so! the fry will eat those thingy's - I have raised fry of rainbows
and blue-eyes in water so green you couldn't see your hand in it. Its great
stuff!
Just add some newly hatched brine shrimp, micro worms etc. every other day
and you will have the best coloured, quickist growing, fatest fry you have
every seen. The only problem is if the tank crashes - in other words, if
all the algae dies quickly for some unknown reason usually most of the fry
will die also - lack of oxygen etc,etc.
>I feed about five times a day just a little. But
>like I said I don't see fry swimming at the top.
You shouldn't be feeding if you can't see any fry?
The only other suggestion I can offer is to keep trying, you know that old
saying - if you don't success blah,blah,blah.
