My Angels are laying eggs!!

I just walked in the other room and saw 2 angels acting strange so I watched
them for awhile, seems they're laying eggs. They swim up to my filter
pick-up tube and a small "tube'" comes out of the under side of the Angels
and they swim slowly up the pick-up and deposit eggs (I think). I don't want
to disturb them and turn the lights on, so I really can't tell what's going
on. Are these females laying eggs, or are these males fertilizing eggs
already there?? I don't want to scare them with the lights, so I can't
really tell for sure. I have 2 other Angels in the tank also, but they are
staying on the other side of the tank just kinda floating around (I know
that's what they do ), but more so than usual. Are they part of it, or are
they just smart enough to stay clear? I,ve had eggs in there before, but
never saw it happening. I'm not at all interested in raising fry, just
wondering since I saw it.
Thanks, Rick
