so the tank wasn't up and cycled before you moved the fry into it? If that
is the case, it is not cycled. You cannot cycle a tank just by moving water
from one cycled tank to an uncycled tank. Your fry need to be in a
completely cycled tank. Especially with the large amounts of food you have
to put in a fry tank to get them to grow and be healthy.

Whatever you do, do not put anything else in that fry tank for another month
or two until it is completely cycled unless you want to lose more fry.
