Those new to caring for bettas can easily harm their fish.
  Therefore, there are a few things you should know about feeding betta fish, especially if you don't want a sick fish on your hands.
  This article will give you a few tips so that you don't harm your pet.
Food In order to feed your new fish, you will obviously need some type of food.
  You can buy flakes and pellets that were specifically made for bettas to eat.
  These two are the most common foods used by owners.
  However, bettas also like other types of foods.
  You can try giving your fish brine shrimp, fruit flies, and blood worms.
  He will definitely like it.
Overeating One of the most important things to remember is never to overfeed him.
  These fish have very small stomachs.
  They're about the same size as one of their eyeballs.
  So, it's very easy to overfeed him.
  Doing so can cause constipation, swim bladder disease, GI obstruction, and death.
  Only give him enough food that he can eat in two to three minutes.
Uneaten Food After feeding betta fish, you should never let the food sit in the tank for too long.
  If you let uneaten food sit in the tank, it will start to rot quickly.
  Rotted food will quickly diminish the quality of water in your betta's tank.
  Therefore, make sure you scoop out any food that he doesn't eat.
Spawning If you plan on breeding your bettas, then you will need to feed the male and female very well before putting them together.
  You should begin feeding them high-quality foods about two weeks before you put them together.
  Good foods to feed include mosquito larvae, frozen blood worms, and fruit flies.
