Important Things to Know for Fish Keepers

  • They have big teeth, which should be checked from time to time because in case it gets big, the fish would have trouble eating. Trim its teeth carefully and seek a fish veterinarian or expert’s help if required. The slightest cut may cause harm to its life.
  • The dogface puffer fish’ beak keeps growing continually. Hence, they need hard-shelled invertebrates as a part of their diet so that their beak does not overgrow their mouth.
  • One of the dog face puffer’s tendency in the wild on sensing danger is to inflate its body by swallowing air or water. They often display this trait in a tank environment, too, especially when stressed. Hence, care must be taken to avoid such incidences. If they swallow a lot of air and cannot get back to their standard size, then it could take a toll on the fish’s life.

FAQs

Q. Is the dog face pufferfish dangerous?

The dogface pufferfish is perceived as dangerous as it possesses tetrodotoxin, a deadly poison that it uses for protecting itself against its predators mostly in the wild. However, it does not sting or bite humans, and touching this pufferfish species will not cause harm as the toxin is present internally and not on its skin or spines.
