Bubble Nest appears; what should I do?

[RussGB]

I have some red dwarf (and a single blue) gourami in my community. I did a water change, and a day later I found good size bubble nest amongst some fresh plant debris floating in a corner. I cant see if there are eggs in there, but if I leave it there and there are, there other inmates will eat them. If I take them out, they are on their own...

What should I do?
