The Dogface Puffer, Arothron nigropunctatus, also known as the Dog Face Puffer, is a peaceful marine species that features large expressive eyes and a sad-looking small mouth. As a voracious carnivore, the Dog Face Puffer will unabashedly devour small inverts but won't damage corals. It is best kept in a tank of at least 35 gallons with semi-aggressive tank mates and plenty of live rock hiding places. Feeding the Dogface Puffer can be difficult, especially if they feel stressed or insecure. They will take a carnivorous diet of shrimp, squid, clams, and crabs or other meaty marine foods, frozen or live.
The Dogface Puffer, like most puffers, have the unique ability to inflate their body to twice its normal size to protect itself from predatory ingestion. Though this is the puffers best known trait, it is advised to never induce this action with your puffer. Further, be sure to never expose the puffer to the air, ever. If the puffer ingests air, it is next to impossible to remove it. Therefore, if ever transferring tanks, be sure to use a container rather than a net to ensure that the puffer is always underwater. They can also be fed the drug fenbendazole to prevent against internal parasites. Overall, this is one of the coolest and most unique marine fish available and every aquarists should care for a puffer at least once.
