Feeding instructions: Simply place the 7-Day Feeding Block in your aquarium or Betta bowl. Within hours it will start to dissolve, releasing nutritious freeze-dried foods, while also neutralizing your aquarium water. One 7-Day Feeding Block will be sufficient for 1-3 fish and will last 7-10 days depending on the PH level and water temperature. A minimum water temperature of 72 Degrees F and PH level of 6.6 to 7.0 will be advantageous for the most efficient release of food particles. Highly alkaline water will slow down their release.
Also try feeding your betta the inside of a pea, which also helps keep Bettta fish regular.

You should feed your betta fish every day with a few pellets. Their stomach is only as big as their eyes so be careful not to over feed.
Many owners like to have a day of fasting for their betta once in a while. This helps the digestive system reducing constipation. Betta fish only need to be fed 2-3 pellets per feeding so one container will last a very long time.

Knowing the right way to feed your betta is fundamental, because not doing it right can have big consequences on your bettas health. Nothing is more stressful than dealing with a sick fish, right? So, let's do it right, and get rid from the calamity!

Here are some golden rules on feeding your betta.

First, select the proper food. Bettas are selective eaters. A betta specific pellet is ok, but live and frozen foods are preferable. The recommended diet includes frozen brine shrimp and frozen bloodworms.

The next rule is to not overfeed your Bettas. Carefully dose the meals, because even if the fish ate all you give him, he will produce so much more waist when overfed and the pollution level of the jar he is in will go beyond safe range, this problem is smaller if you keep your betta in a larger aquarium. Remember not to leave uneaten food in the Aquarium! Once your betta and rest of the fish is done eating, you must remove all uneaten left over food. If you do not remove it, it will punctually rot and cause havoc in the tank.

Bettas prefer to eat from the upper parts of the water column. They don’t really enjoy eating from the bottom of the tank. So before dropping the food in the tank, make sure you have his attention. Let him see the food, get it close to his face from the outside of the aquarium, let him check out what it is, and then there you go! Drop food in front of his nose. The best way is to drop a tiny bit of food--about 6 frozen brine shrimp, watch the bettas eat it all and then look at the belly, if it looks the same as it did before you fed, it’s ok to give them more, but always watch and make sure to make the second portion smaller than the first.

Your betta should go for the food right away, but if not, watch where the food sinks, and what the betta does. If more than 15 min he has not eaten the food yet, remove the food. Never let the water go cloudy. If it is already, then change it, as cloudy water will threaten your betta’s health. Normally, small bowls or containers should be changed at least twice a week. Larger tank can be changed once a week. And notice if the ammonia and nitrite levels are up the roof, because both are very bad for your Betta. Also be wary of harmful bacteria they can ruin your fish life, but don’t kill of all bacteria in the aquarium since a lot of bacteria is essential for a well functioning aquarium.
One of the biggest things to keep in mind with betta fish is that just like with other fish, they are prone to overfeeding. Fish may be awesome pets, but they definitely are not the smartest creatures out there, and that means that they will continue eating and eating until they pretty much blow up. A betta fish should be fed twice per day at most and you should only feed them little pinches at a time. How often do you feed a betta fish is a common question so we decided to dedicate a post that covers everything you need to know about Betta feeding and diet.Just be sure not to over feed them as the flakes can swim around in the water and pollute it if left uneaten. It has been noted that some betta fish do not like flakes, which is something that you will have to figure out on your own.
