Hi Bernie and
It would be good to know what species you have. Any pictures?
Generally, it is very hard to raise baby octopuses because they have a sort of planktonic stage (which means that they are not bottom dwelling like adults).
It is easier to raise baby cuttlefish which are born as mignature adults.
However, it is not impossible and you should give it a shot.
Firstly, it is important that you do not disturb the embryos, you don't want them to hatch prematurely.
Secondly, you will see that the hatchlling are very small (3 to 8mm total length) and you should becareful they don't get trapped in your filter. Also, be sure that your inflow of water is gentle.
As for the feeding...mmmm well that is the tricky part!
The best would be crustacean larvae, but zooplankton should be fine too. Try to feed them small amounts as many time per day as you can!
You would be lucky to have two or three that survives...
Good luck and keep us posted
