No DD toys they are from males and females. I put the males and females in separate tanks, turn up the heat (via an old water bed heater) extend the daylight hours via a kambrook timer switch and lights (so they think it is summer) and then put the boys and girls together and wammo! usually get 70-80% berried (that is with eggs) within a couple of weeks of that.

300-500 eggs each female so plenty of yabbies. Takes 3 months for bait size and then 6 months for good eating size.
