Kris I am sorry I missed this post. I will tell you that most bettas will not bother flake food unless they are really hungry. This is why I feed the betta first if they have tank mates and then go to the far side of the tank and put any flake food in that I have to feed and they will not bother to chase it down. Bettas are picky eaters and unless they have not been fed themselves they generally will not bother the food of the other fish and tetras are much quicker fish swimming than bettas and can beat the bettas to the food any day.

If he does eat a mouthfull of flake it will not overfeed him to the point of being sick. It is when they are given double or triple the amount they should have that it becomes dangerous to them. When you open the tank and dump in the food for the betta and he has way more than he should have of the high protein food that is made for bettas you will be in trouble. But a flake piece here and there is not going to get him in trouble. The tetras are not going to let him have that much of their food.
