I always feed babies betta with yolk solution 7-10 days before give them another food type.
This is methods step by step to make the yolk solution for the babies betta :
1. Cook chicken egg by put it in boiling water.
You will get this..
2. Choose only yolk..
3. Put it in a large water and disperse it..
4. Strain it and now it is ready for use for children/babies betta fish..
5. Use your hand to drop this yolk solution in betta babies tank. Drop a little of it around their tank.
Don't drop a lot of yolk solution each time you give the babies food because water condition will bad.
Give the betta babies this yolk solution 1 time a day is enough.
The End...
