Down Breeding
Behaviour These fish are almost always "in the mood", they spawn once or twice every week. They are also always pretty active, either searching for food or swimming up and down the glass looking for a spawning site. Today they spawned all day, I saw the first group of around 50 eggs laid on a floating plastic container already holding older eggs at about 7:00 am this morning. By 10 pm there were 5 clusters of eggs on outside of the floating container, total of 167 eggs.
Eggs There were 167 clear to white eggs laid which were 1.7mm in diameter.
Segregation Eggs removed to hatching container, one Alder cone and moderate aeration added.
