Baby fish eat brine shrimp. It's as simple as that.
Fortunately, baby shrimp are very easy to hatch.
The brine shrimp are about the size of the head of a pin.
The angelfish need to be fed about four times a day because their little tummies can't hold much at a time. If they are fed less often or not enough food, the weaker ones will starve.
I use San Francisco Bay Brand, which is known as a quality product.
Very soon I will begin feeding the two-week old angelfish some tiny flecks of dry fish food so by the time they are sold to the pet store, they will be well prepared for someone's aquarium.
