Right after the fries has hatched, after how many days do we start to feed them with artemia? Do we need to do the enrichment for the artemia? What is the appropriate size to remove the babies from their parents?
1. I suggest you allow the parents to nurse their babies (Breast-feeding) for the first week. On the second week you will start to feed them artemia. Feed them newly hatched artemia (24 hours) little bit at a time. Then slowly increase.
2. There is no fix rule or time to separate them from parents. If you want them to produce more batches, separate them earlier and let them spawn again. If you intend to keep this batch for breeding stock, allow them to be with their parents until 20 cents coin size. They will develop parental love to care for their babies later.
