| On the African tank if they are not juvies they are fine being feed every two days.
They aren't being nippy because of your feeding schedule, they are nippy because they are African cichlids, its just what they do.
I would not use feeding blocks if it were me, chances are you will just foul your water.
The reason people over stock African tanks is to curb the nipping issues, in my opinion it has nothing to do with you feeding every second day.
If you feed every second day I would continue to do so.
I have some tanks that get feed everyother day and some that only get fed 2-3 times a week. While this wouldn't work for community fish it is fine for an adult cichlid tank.
Just to give you an idea when we went away for 6 days about a month ago I didn't have anyone feed any of my tanks. All were fine, except I lost about 5 neet fry. All other fry and fish did fine, I really expected to lose more fry.
