Maybe someone can help me.  I have just hatched out four different species
of killies.  I would like them to grow fast.  I have the fry now in shoe
boxes.  I put about 30 fry in each box.  First, is that too many fry in
each box?  Secondly, if I kept that many in each box, how often would I
have to change their water for them to grow fast, and not be stunted for
lack of space.  And if I fed them twice a day on micro worms and brine
shrimp, how often would I need to change their water? >>

I ran an experiment once with Austrolebias bellottii fry in shoe boxes. 
Everything was identical with about a dozen fry in each. In one box, I manually 
changed the water about 30% every other day, my usual practice which sometimes 
was neglected. The other box I hooked up to my automatic water changing system. 
It was changed about 20% twice a day. The fry in the shoebox that was changed 
twice a day grew three times as fast as the other box. Not statistically 
sound, but enough to convince me to hook up every container I possibly could to 
automatic water changing. In another experiment I ran at the same time I had 3 
Aphyosemion australe fry in a similar shoe box hooked up for automatic water 
changes as above. In three months those fry turned into a trio which were 
producing young in the shoe box.
