It's interesting. I use film canisters for my males to build nests in, and they keep all the fry with them in there for around 3-4 days. During this time the female will usually help pick up any fallen eggs or fry and put them back up in the nest and defend against the fish in the neighbouring tank.
Then once the fry become free-swimming the male completely forgets about them. He doesn't do any further care and so I have tanks that have fry of all ages swimming around as I can't catch them all.
Three of my males have just been living in their film canisters lately. As soon as the newest batch of fry leaves the nest they spawn again. I swear they have been spawning 2-3 times a week lately.
It's interesting that splendens males seem to be a lot more involved with caring for their fry, even after they leave the nest.
Nothing better than a great dad though! They make the whole process so much easier.
