Eggs that prove infertile, often becoming covered with fungus should be removed. However, effort should be made to find out why they do not hatch in the normal way. It is often found that some, or even many, eggs are covered with fungus but it is rare for all to be bad.
Snails eat eggs and should be removed from the breeding tank. But in rearing tank, snails help to keep the bottom clean. They too do not eat the fry.
Why eggs are infertile?
Wrong temperature
Too much or too little light
Dirt
Infected infusoria culture that breeds fish enemies or harmful bacteria
Unsuitable water that might contain harmful gases. We can either filter or use rainwater to avoid this problem.
Water PH. If new water has been used, try ‘seasoned’ water. Leave tap water in bright light for a day; without disturbing the precipitate that will have formed at the bottom, siphon off the water in to another clean container and leave it there again in the sunlight to mature for a further twenty four hours or forty eight hours. The siphoning gets rid of any insoluble or floating matter.
Eggs not fertilized: due to the pair of adults do not harmonize. We can use two or three males to one female.
The tank is too small.
