  • Use a filter to keep the water clean.
  • Change the water regularly.

Tank Decor:

  • Provide hiding spots like plants and caves.
  • Avoid sharp decorations that can harm your betta.


  • Betta fish enjoy exploring, so add plants and decorations for them to swim around.

Diet and Nutrition

Proper nutrition is vital for keeping your betta healthy and thriving. Here’s a quick overview of what you need to know about their diet.

What to Feed Your Betta Fish

Bettas are predatory fish, meaning they primarily eat other small animals in the wild. Their diet should consist mainly of the following:

  • Pellets or flakes: These are specially formulated to meet a betta’s nutritional needs.
  • Freeze-dried or frozen foods like brine shrimp, bloodworms, and daphnia.
  • Occasional live foods like mosquito larvae or small feeder fish.

It’s best to feed your betta 2-3 small meals daily rather than one large feeding. This helps prevent overfeeding.

How Much to Feed Your Betta Fish?

The amount to feed will depend on the size of your betta, but a general guideline is as follows:

  • Small bettas (under 1 inch): Feed them 2-3 pellets or a small pinch of flakes 2-3 times daily.
  • Medium bettas (1-2 inches): Give them 3-5 pellets or a small pinch of flakes 2-3 times daily.
  • Giant bettas (over 2 inches): Feed them 5-7 pellets or a small pinch of flakes 2-3 times daily.

It’s important not to overfeed, as this can cause swim bladder issues and other health problems. Always remove any uneaten food to keep the water clean. 

Remember, proper feeding is just one aspect of caring for a healthy betta. Maintaining good water quality, providing the proper tank setup, and giving your betta plenty of enrichment is vital for their well-being.
