It is better to raise pufferfish alone, because pufferfish have a mixed diet and feed on fish, shrimp, crabs, and shellfish.

The teeth of puffer fish are healing teeth, which are beak-shaped. If the bodies are in contact with each other or the density is too high, they have the habit of biting like crazy. The body length of puffer fish that cannibalize each other is about 5 mm. At this time, its teeth have been initially formed.

Extended information

The puffer fish has a round body and mainly relies on its pectoral fins for propulsion. Although such a body can rotate flexibly, it is not very fast, making it an easy target to hunt. Therefore, puffer fish have evolved a self-defense mechanism that is very different from that of ordinary fish.

When the puffer fish is threatened, it can quickly suck water or air into its extremely elastic stomach and expand to several times its size in a short period of time to scare off predators. The spiny pufferfish in the family Acanthidae even has spines on its body. When it swells, the spines on its body will stand up, making it difficult for predators to eat.
