A good daily portion of food for an adult betta is about 1.8 grams, but it doesn’t have to be exact. This applies regardless of the type of food you are feeding your betta. A betta keeper is not expected to meticulously weigh out 1.8 grams of food everyday, especially when a betta is on a diet of different types of food. However, if you are unsure of the amount to feed your betta, you may like to weigh out 1.8 grams of your chosen food the first time you use it so that you get a rough approximation of what the portion size should be. Some bettas will happily consume more than 1.8 grams, and you do not need to strictly adhere to this number, but it’s a good amount (as a rule of thumb) to aim for in order to maintain the health of the fish 😁 
I really enjoy and rely on your site, and wondered if you’re still taking questions. I gottten some frozen brine shrimp in a grid of little packets and am wondering what I’m doing with it – how long will it take the betta to eat through one packet, and should I’m keeping that portion in the fridge or the freezer? How to chip off a portion? Do I’m had letting it thaw to room temperature?Sorry, I’m knowing this is a pretty small question and one that I will eventually figure out myself, but I’m a new fish owner and don’t want to do anything wrong.

Hikariusa.com goes on to describe how owning a betta is a wonderful way to start a fish keeping adventure. Even though the above tips are highly recommended in order to maintain a healthy and productive living environment, they are by no means an entire handbook. Strike up a conversation with a local aquarium or fish seller and get additional guidance on best practices for making sure that you create a happy and healthy home for your betta. With proper betta keeping techniques, you can extend the life of your betta in a big way. We’re havinge having a number who have lived more than 5 years with the record over 8 years and counting!

Bloodworms or Glycera are the larvae of the midge fly and can be found in pools and ponds of water. Betta fish commonly gorge on them in the wild, making them ideal variations for even the pickiest of eaters. Betta’s put on a big show when going after these guys, but they shouldn’t be used as the exclusive source of food because they lack amino acids. They are high in iron content, resulting in their bright red colouring. If you can’t handle the live option (they are pretty gross looking), they also come in a gel or freeze-dried option.
