Eggs? What do they look like? If they are in a gelatinous mound they are snail eggs and you might want to rinse those away. If they are fish eggs I'd personally let them hatch, if they will at this point, and see what you get.
I recently completely dismantled my 40g African setup, sold all the fish, cleaned out the tank and started over with new substrate, rocks, wood, plants, etc., since I want to make this a South American puffer tank. I was letting the plants settle and essentially running the tank empty while I mulled over my options. Lo and behold, one day I see six fry swimming around in there. I was delighted. Since there are no predators, I'm letting them grow and see what I get. They had to come from eggs off one of the plants, but I did not notice them, and they survived the rinsing I did before planting in the tank. Too cool!
