While a baby betta or betta fry weighs only about 0.02 to 0.05 grams, a growing betta fish can weigh at least 3 grams to 3.5 grams, especially if it is healthy. And as the fish grows older and larger, it can gain more weight and can end up weighing around 3-4 grams or more. Bettas are carnivorous and live on insects and insect larvae.
Live Food: Betta fish like hunting. You can give them tiny live foods like fruit flies, earthworms, or mosquito babies. It’s fun for them and natural. Frozen Food: If you don’t want live food, there are frozen options too. Things like frozen shrimp or worms can be a treat for your Betta.
If your betta fish is looking a little under the weather, there are some things you can do to help them feel better. First, check the water quality in their tank. Ammonia and nitrite levels should be at zero, and nitrate levels should be below 20 ppm. If the water quality is good, then the next step is to look at your betta’s diet.
