Down Breeding
Behaviour Each of three spawnings occurred after the fish were moved into a new tank, followed by large water changes, using 50% rain water. Surprisingly, the fish spawned three times in months, with a total of at least 300 eggs. In each case, I removed all the adult fish from the tank. In each case, some fry have survived, but it's not clear how many.
