Now that the angelfish are four weeks old, I have switched to dried brine shrimp instead of live. By crumbling it into the water, it's larger than freshly hatched shrimp and a bit more filling.
Within the next couple of weeks, I will be adding dried fish flakes to their feeding. By the time the angelfish are between eight and ten weeks old, they will have been weaned completely off the brine shrimp and First Bites and will be eating a diet consisting solely of dried fish flakes. This allows them to settle in much more easily with a community tank.
