Adding Fry to Display Tank

[Moe]

My emerald corydoras laid eggs on New Years Eve.  I pulled them and have them in a grown out 10 gallon.  There are 19 of them and they are growing fast.  Does anyone have any advise on when it is best to add them to my display 75 gallon?  Maybe there are only obvious answers like "when they are large enough to not get eaten" but is there any other advise out there?  It's a peaceful community tank with rummy nose, bosemanis and seven corys - and one very peaceful apisto.

 

My thought is to move them when they are larger than the apisto's mouth, but I looking for additional advise.  This is my first batch of fry.  Thanks!

i think the move them when they are large enough to most likely not get eaten is likely the proper approach.

Wait till they big enough not to get eaten

Yeah, the longer you can stand over feeding and over water changing on the 10 gallon, the better for them. At some point you will be fed up with the maintenace and that is when you will move them. But for them, the longer they go without needing to compete the better.
