Most Betta Fishes Don't need alot of food!!!!!
Feeding Schedules are important for those getting fish!!!
You should feed your fish three times a week at maximum!
A Weekend Feeder is a great idea too... It lets of food every so often to keep them feed and hydrated!!!
Flakes are good for your fish as long as they have nutrition...you should aslo try to get one made especially for betta!!!! Freeze Dried Blood Worms are a nutrious food but should not be used as regular food. Think of this food as snacks or desert no more than once a week should your betta eat these!
