Breeding Discus Part 3
Posted on
We will now go over what to expect after the eggs have been laid. This is where the frustration starts. The first two issues that you will be confronted with are eating of the eggs, especially by the male, and infertility. We will go over the eating of the eggs first. We will go over fertility in the next part of the series.
The number one problem, and the one you must get past, with breeding discus is the eating of the eggs by the parents. While both parents will eat the eggs, the male does it more often. This is often done as they spawn and there is very little you can do if this occurs while spawning. The female will make her egg-laying run and then the male, instead of following her with a fertilizing run, will follow her and eat the row of eggs. This behavior is most common in new pairs. A majority of new discus pairs will eat their eggs. Fortunately, they will often stop this behavior as they become a more mature spawning pair. If you get lucky and they do not eat their eggs when spawning, there is a good chance that they will eat them before they hatch. Fortunately, if you get this far, there is something you can do. You can, at this point, take the eggs out and artificially raise them or you can take a mesh screen (house soffit screen works very well) and fit it directly over the eggs. This will allow the discus to still blow on the eggs and bond with them, but will keep them from eating the eggs. Obviously, you will need to have planned for the spawning and will need to have created the screen prior to the actual spawn. If the eggs do not get eaten and are fertile, they should hatch out in three days and become free swimming in about six days.
