The next day I had a tank full of eggs! I have now separated Lottie (the female) into a different tank so we don't have a repeat of this in a couple of weeks! I have left the eggs in the tank where she originally laid them, a lot of them don't look like viable eggs, which isn't a problem as I'm already raising 3 week old larvae from her previous batch!
I will pick out 20 or so larvae that hatch to bring on. I started with around 30 with the last lot and am down to 9, so on that percentage it shouldn't be too much trouble to rear another small batch!
