I usually skip a day feeding once per week, and sometimes feed twice a day, but when I feed twice, its quite small amounts, especially if I happen to mistakenly feed too much at one time, then I don't feed again that day. I find for many cichlids, a day of only algae based food is a good thing.
I believe most fish keepers probably feed too much, if bellies are bloated, I would say that's too much.
Fish don't really have an appetite shut off valve, because in nature its often feast of famine, and most fish don't get to eat every day, so when they do come upon an abundant food source, they gorge.
In the artificial confines of a tank, this constant glut can be counter productive to their healt, and their instinctual feast or famine response does not change just because they are in a tank.
Too much constant food, with not enough fiberous material to push proteins thru the gut, may be one of the reasons we see so many digestive tract infections in the disease section.
I haven't kept fronts in a long time, but recall them to be slow at grabbing food, so I had to choose tank mates carefully to also allow them access to what I did feed
By the way, in reference to what ad88 mentioned, since your tank is only two week in, how did you cycle the tank before adding all those fish?
With household ammonia? or sacrificial fish?
Did you use seasoned filter media? or substrate?
It usually takes 6 to 8 weeks of cycling before you add a sensitive species like fronts.
