I have a yellow discus breeding pair they lay eggs but then they eat away, once the young ones had hatched but after few days the parents ate all the baby. and I like to tell you that the male fertilizes the eggs every time
1. The location of the breeding tank is important.
2. They should not be disturbed.
3. Otherwise they will eat up the eggs.
4. They will even eat up the larvae or fries.
5. Try again.
