Any other fish in the tank besides the parents?
I had guppy fry in my community tank ages ago that had the parents and gouramis and a few other smaller fish. Some will get eaten, but it really helps having lots of plants.
Java moss is a good one - very easy for the fry to hide in. I remember thinking all my fry had gone, and then one day I saw the cutest little face peeking out form the java fern - made my day

I would keep them in the net for a week or two still. Unless it is really stressing them out (other fish can see them and try eating them through the net - happened to me!).
