Your male will try to breed as long as ripe females are available. He won't
care if they have ripped fins. To get him out of spawning mode, you might
have to separate him. Even without females, the nest building is an
expression of good health.
The eggs hatch in about 36 hours. By the time you moved that first nest,
most of the fry would have moved on, and probably became a meal.
In a way, it's a bit of an advantage for you that the fry numbers are low.
Imagine how many tanks you would need if all of the up to 1,000 eggs from
each spawning hatched and the fry survived.
