Hi Eric,
The baby's are doing fine and yes, just before I left for my holidays I released them into the main tank with the adults. They don't grow exceptionally quick, the biggest are around 2cm now. They still only feed from the surface, the adults will also feed from the bottom. So you really need some floating baby foods.
And I found out you can't keep younger fry with the older ones. They will be eaten! I put 25 L309 wigglers in the little fry box, a day later only 5 were left.... My 1,5cm Oil baby's were fat....

They will also certainly eat baby wiggler Oil cats so that's why I never had any more luck after the first lot. Now I know I will have to raise each batch separately. Just something you learn along the way
Here are some pictures of the biggest juveniles at their release: (sorry for the phone pics..)
