1. Don’t worry. They are going to be ok.
2. Hole in the heads is very common. They are not going to kill your fish.
3. The cause of hole in the head is due to your diet imbalance.
4. It’s lack of Calcium in the diet.
5. Mix milk or spirulina in your fish burgle. They consist of calcium.
6. Once a while give them Methylene Blue and salt bath.
