My 29G is over run with Platy fry when I decided to put a divider in and let the fry grow out. Well somehow through the side of the divider they kept coming, 10, 15, a ta time, a few weeks later another 20 show up.. (its still happening).
I have them growing out in a 5G, and looking for a larger tank. They will go in the paper or Craigs list, somehow I'll find homes for all of them. Except for the blue platy fry

I would caution anyone wanting to know how to raise fry, because you will have FRY and plenty. Platys are rabbits with fins. What happens after seeing those cute little faces for weeks and THEN you need to find a bigger tank, lol.
Heres a few close ups of my little wee ones, about 3 weeks old.
