I just want to be sure I'm not starving my fish. My tank is a few weeks old, and I have four zebra danios, a pair of guppies, and now at least six babies. (the female had babies yesterday) I've been feeding them flake food once every day, no more than what they can eat in 2-3 minutes. I'm also crushing some of the food for the babies. Do I need to feed them more frequently?
