Kinda depends if you want to keep the fry or not.
It is generally frowned upon to keep hybrids and try to sell them or give them away. But if it's the same species breeding and you want to keep them, probably best off putting the holding mom in a "maternity tank". Once she spits the fry you can either remove her back into the main tank,and leave the fry there, or let her recover some strength for a while first.. she'll be drained from not eating for so long.
