Hey Fruju. Well done on the spawn. The Agassizi are very nice fish. I bred these a few years ago and ended up with about 60 fish.. Only 4 males from memory. And yes the eggs will be a light orange/pinkish colour but will quickly turn whitish if infertile. I usually left the parents with the fry until free swimming then removed the male. I would leave the female with the fry for a good while to give them a good start. And as you said, they may eat the first batch. Just be wary of the female with eggs as they can be very aggressive to other fish, including the male, when protecting the eggs. Good luck
