Parents should now be separated. After the fry emerges out, they can be fed infusoria or crushed flakes as they can eat very small food.
Common DiseasesThey are easily affected by red blotch disease. This is seen as bloody sores on their belly. This is caused by the water condition and low oxygen level. Another common disease is Ich- white spot disease. This is caused by the addition of new fishes in the tank and unclean tank equipment.
