Behaviour The largest male would swim up beside either of the two present females. He'd then swim directly beside her and swim around with her in laps around the aquarium. After so many times around, the male would begin shaking and they would release eggs and sperm.
Eggs There were 20 clear eggs laid which were 3.0mm in diameter.
Segregation No eggs made it. I wasn't expecting them to breed in just 5 days after being taken from the wild and I didn't have a fry tank prepared so I just let the other fish present in the tank (a 3" Green Sunfish) and the Chubs eat the eggs. I'll be more prepared next spawn.
