Notes on raising pufferfish:

1. Breeding pufferfish requires clear, pollution-free water and rich oxygen content. The water temperature needs to be controlled at 16-23 degrees, not lower than 9 degrees, nor higher than 28 degrees. Pufferfish like brackish water bodies, and the salinity of the water body is 6%-13%.

2. Small pufferfish are highly aggressive, ferocious in temperament, full of hostility to other fish, and prone to attack other fish, so it is best to keep them alone. If you want to breed them together, you can arrange some larger fish so that the pufferfish cannot attack.

3. Pufferfish likes meat and can be fed some aquatic insects, fish, shrimps, snails, clams, etc., just once a day. Occasionally, you can also feed some stem and leaf vegetables to supplement trace elements.
