There is nothing like a balanced mixed diet...
I once read the results on an experiment with guppies where the fry, devided into control groups, where some fed single types of food, and some a variety of foods at every meal...
The bunch which got the larger variety in food did not only grow bigger, but the tails were noticably better developed with very few small tails.
P.S I believe in watching my fish eat at all times, this way you can observe for any fish not showing appetite and spot uneaten food... (with angels its hard to overfeed, the keep begging even when there stomach looks like marbles.
Lots of small meals are much better than large meals.
But then again, I have alot of time...
