Getting aquarium plants to flower, pollinate and seed is not usually easy (or even possible for most of us) so lucky you. Well done.
I checked with Peter Hiscock (his book, not the author) about seeds and he suggests that it is better to plant the seeds in damp soil in a small glass container (an unused small tank, goldfish bowl, even a jar) and add water when they sproat, keeping the leaves under water as they grow; transfer them to a regular aquarium at about 4 inches with 4-5 leaves. Alternatively, plant as before in damp soil and grow them emersed until about 4 inches tall, then transfer them to an aquarium. Almost all nursery raised aquarim plants are grown this way, emersed, which is why their leaves look different from those they develop when we plant them in a tank.
He also says you must plant the seeds immediately, not leave them.
