After 60 hours (dependent on water temperature) the eggs hatch. The young will
be placed, by the parents, on a different place of the cone, until the moment of
swimming on their own. After 48 - 60 hours, the first young will already swim
free. At this moment, a large deposit of skin excretion is formed. Quickly after
the first strokes the young fish will swim in the direction of the parents, to
feed of the skin excretion. This excretion is the only means of food the young
fish will eat in the next few days.
We can start feeding artemia-naupliėn after five days. From this moment on this
becomes the main food for the young fish until they can cope with larger food
species. You have to spread the daily supply; this fish needs, during the day.
To raise the fish good and properly you should feed them at least ten times a
Naturally these large amounts of food cause large amounts of waste. Therefore
you should refresh your water daily at least 30% to acquire a reasonable water
quality. As the little fish grow, they will eat more, thus the water refreshing
becomes increasingly more important.
Most Asian breeders refresh at a rate of 100 % a day.
Considering the above facts you need to invest a lot of time in breeding discus
fish. Therefore think before you start the hatching process with these fish.
Although this fish is one of the most interesting aquarium fish, I have to
dissuade a lot of people to start hatching. The badly bred fish will not reach
its full growth and will not be able to grow into real beautiful discus fish.
