Wow, I didn't realize I was mentioned so much! Flattering.
Ivan, you aren't overfeeding, unless you mean too much at each feeding?
5 times isn't excessive. The fry need small meals often, because their stomachs are smaller but they need lots of food to grow on. It's best to give some kind of high-protein maybe once a day, and the rest can be whatever you want. However, when you do feed high protein, don't make it much. Live plants in the tank will be your best bet if you can't feed that often, because the fry can eat the organisms off those and it will kind of make up for it. I wouldn't recommend feeding many high-protein foods if you do that though.
