I have picked Rainbow eggs into floating trays and this does work. Gary
taught me to use a bit of shell grit if the water tends toward a lower pH,
and to pick the eggs from the mop onto small pieces of yarn. I have also
done this successfully onto JavaMoss. If the small container gets any light
then I think the moss helps to keep up H20Q. If you use yarn you can also
use a fungicide such as Meth. Blue, but the moss doesn't like this very
much. If you float the containers in the tank you plan to raise the fry in,
you can do small daily water exchanges from this tank and they fry will be
pre-acclimated to that water... makes it a sinch to let em go into the big
tank when it's time. :-)
Having played with killies somewhat, I have picked up a few habits that may
or may not be good. ;-) I currently have about 8 new rainbow fry that I've
hatched out in a 1 gallon jar. The jar has a cover and a slowly bubbling
airstone plus some JavaMoss/Fern. For small batches of eggs I have found
this works very well for me and I can put the jars up high in my cool
basement fishroom to keep them warmer, can move them and find room for them
easily, and can monitor food levels better (I use vinegar eels as first food
and it is easier to see them in a jar than a tank -- I can lift the jar and
look through a light source to check to be sure they still have food). If
you think this is a small container, you should see what I use to hatch out
killi eggs! ;-)
If I didn't use the jars, I would be mixing mops from different spp into one
tank, and when I do this it seems I never get enough of the fry I want
raised up, just mostly one kind. This way, all the fry are hatched and kept
separately so I know how many I have of what spp. I then mix them together,
but only once they are old enough to be able to tell them apart. I don't
have enough tank space to give each species of fish I breed it's own tank
for hatching and growout. Without the jars, I'd have trouble. They don't
take up so much space and it's relatively easy to add "just one more" if I
need to.
