The chances are that the gudgeons will eat any eggs before they have chance to hatch, I'm afraid. They may be mainly bottom dwelling fish but when faced with a tempting snack, they do feed from the surface.
The honey gouramis I've had over the years did manage to produce fry even in a community tank. But even the ones I 'rescued' into a breeding net did not live long. Anabatid fry fry need warm humid air over the water for the first few weeks and I think it was lack of this in my tank which caused their demise.
If the first set of eggs are eaten, they will spawn again. Something to think about is setting up a small tank to raise fry if you would like to try this. You would need a very gentle filter flow for fry; an air pump powered sponge filter is ideal for a nursery tank.
It's interesting with that both of the fish species you have chosen, it's the father that looks after the eggs
