Thanks for all your feedback so far. I decided to take the simplist approach and do nothing. So far they're doing great.
It's been 2 days now since the eggs were laid and this evening I noticed little wiggly tails poking out. I was dismayed to see the male angel start to eat them when this happened, but then noticed he's moving them to the filter outlet. It was pretty cool. He would take one of the wrigglers in his mouth, spit out the shell and the wriggler, then recatch the fry and move it to the new spot and go back and eat the shell. I've since turned off the filter and am now just running a sponge filter.
