Could either, keep them in a over stocked tank...
Give them to your LFS for store credit (minimum) or free.
Or kill them it your choice on what you do with your fry.
3rd option is not one I like to see but it does happen, especially if you leave the fry in the same tank as the adults, basically its fair game as this happens in the wild too
The other 2 options are perfectly fine provided you can do large water changes and have over filtration if you're planning on overstocking that tank.
Personally I prefer option 2 if you can return to LFS for some store credit IF they still do that, finding now most LFS wont give credit anymore unless a rare or desirable specie.
Failing that, asking family or friends who have tanks if they want some free cichlid provided they have suitable tank set ups and stocking.
Next option would be to advertise your fish for sale or for free in local papers or online.
A few options really, choice is yours
and good luck.
